20220137529 | TONER CONTAINER INFORMATION ACQUIRING METHOD, TONER CONTAINER SORTING METHOD, TONER CONTAINER PULVERIZING METHOD, TONER CONTAINER PROCESSING METHOD, AND TONER CONTAINER MANUFACTURING METHOD - A toner container information acquiring method includes: measuring a toner amount contained in a resin forming a toner container; and acquiring information regarding mechanical strength of the toner container based on the measured toner amount. | 2022-05-05 |
20220137530 | IMAGING SYSTEM WITH NON-MAGNETIC REGULATOR AND SECONDARY REGULATOR - An imaging system includes a stirring device to stir a developer, a rotatable developer carrier to carry the developer a non-magnetic regulator, a secondary regulator, an excess developer conveyance path extending from the developer carrier and between the non-magnetic regulator and the secondary regulator, a toner supply path to supply a toner to the stirring device, and a merging portion where the toner supply path and the excess developer conveyance path merge. The non-magnetic regulator and the secondary regulator regulate the thickness of the developer carried by the developer carrier. Excess developer from the developer carrier is conveyed via the excess developer conveyance path. The merging region controls the supply of the toner from the toner supply path to the stirring device based, at least in part, on an amount of the excess developer received from the excess developer conveyance path. | 2022-05-05 |
20220137531 | IMAGE FORMING APPARATUS - An image forming apparatus includes: an image carrier configured to carry an image; a developing unit configured to develop the image carried by the image carrier with a developer; and a developer replenishing unit configured to supply the developer to the developing unit, the developer replenishing unit being configured to predict, in advance, an amount of developer consumed by the image carrier at a start or an end of image formation apart from developer consumed in the image formation, to replenish the predicted amount of the developer. | 2022-05-05 |
20220137532 | IMAGE FORMING APPARATUS FOR REGULATING REMOVAL OF DEVELOPER STORAGE PORTION, REGULATION RELEASE METHOD - An image forming apparatus includes an image forming portion, a first release processing portion, and a second release processing portion.
