20100226682 | DEVELOPER CONTAINER, DEVELOPING DEVICE, AND PROCESS CARTRIDGE - A developer container, which contains a developer to be supplied to a developing chamber in an electrophotographic image forming apparatus, the developer container including: a partition wall partitioning the container from the chamber; a conveying member conveying the developer to an opening in the partition wall to supply the developer to the chamber; a sealing member attached to a wall surface of the partition wall to cover the opening; an extending portion extending from the sealing member to an outside of the container, wherein, when the extending portion is pulled, the sealing member is separated into a remaining portion and a removal portion, and a free end of the remaining portion is positioned below an upper edge of the opening; and a spacing holding member disposed between the wall surface of the partition wall and the sealing member to hold a spacing between the wall surface and the sealing member. | 09-09-2010 |
20120177401 | DEVELOPING APPARATUS, PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS - A developing apparatus includes a frame supporting the developing roller; a sealing member provided at each of one and the other ends of the developing device frame and contacted to the developing roller to prevent leakage of the developer; and a developing blade contacted to the developing roller to regulate an amount of the developer carried on the developing roller, the developing blade having a free end in a downstream side with respect to a rotational moving direction of the developing roller, wherein each of one and the other ends of the developing blade is provided with a projected portion projecting in the rotational axis direction between the developing roller and the sealing member. | 07-12-2012 |
20120269545 | PROCESS CARTRIDGE, DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS - A developing device for use in image forming apparatus includes a developer bearing member configured to carry a developer for developing an electrostatic latent image to be formed on an image bearing member, a frame member configured to support the developer bearing member, a charging member configured to charge the image bearing member, a developer regulating member configured to regulate an amount of the developer to be carried by the developer bearing member, and a moving member configured to be rotatably disposed on the frame member and to support the developer regulating member, the moving member pressing the developer regulating member against the developer bearing member by a force received by contact of the charging member with the image bearing member. | 10-25-2012 |
20130009355 | SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS - Provided are a sheet feeding device capable of preventing the occurrence of failure in sheet feeding and degradation in quality of printed matter with downsizing achieved and an image forming apparatus provided with the sheet feeding device. | 01-10-2013 |
20130181392 | SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS - The present invention is directed to a sheet feeding apparatus including a sheet feeding unit capable of feeding sheets stacked on a sheet stacking face of a sheet stack tray, wherein the sheet feeding unit includes a feeding roller configured to feed the sheets, a driving motor configured to rotate the feeding roller, a lifting member configured to move at least edges of the sheets in a direction of the feeding roller, a sheet-shaped member connected to a front end of the lifting member at the downstream side, and a counter member disposed opposite to the feeding roller to pinch the sheet-shaped member, wherein, when the feeding roller is rotated, the sheet-shaped member is moved to the downstream side to cause the lifting member to move, and when the sheets are brought into contact with the feeding roller, the contacted uppermost sheet is fed by the feeding roller. | 07-18-2013 |
20130195519 | IMAGE FORMING APPARATUS - An image forming apparatus sequentially transfers toner images formed on a plurality of photosensitive drums onto an intermediate transfer member or a transfer material to form an image. The image forming apparatus includes an intermediate transfer belt provided with electrical conductivity, and a power supply for applying a voltage to a secondary transfer roller to pass a current from the secondary transfer roller to the plurality of photosensitive drums via the intermediate transfer belt, thus primarily transferring the toner images from the plurality of photosensitive drums onto the intermediate transfer belt. | 08-01-2013 |
20130322932 | DEVELOPING DEVICE, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS - A developer regulating member is rotatably supported. A distance from the rotation center of the developer regulating member to the center of a developer carrying member is more than a distance from the center of a shaft portion to the leading edge of an elastic member and the bending angle β of the elastic member which is calculated from β=PL | 12-05-2013 |
20140363210 | DEVELOPER SUPPLY CONTAINER AND IMAGE FORMING APPARATUS - A developer supply container for an image forming apparatus includes a container shell; a developer accommodation bag contained in the container shell; a developer discharging path for discharging the developer from the bag an outside of the developer supply container; an air fluid communication path for fluid communication between inside and outside of the container shell; and a maintaining portion sealing the air fluid communication path to maintain a pressure inside the container shell in a negative pressure state, wherein the developer accommodation bag deforms to discharge the developer, by the maintaining portion opening the air fluid communication path to permit air to enter the container shell through the air fluid communication path. | 12-11-2014 |
