20150338823 | IMAGE FORMING APPARATUS - An image forming apparatus includes a communication portion arranged inside a cover covering an image forming portion in the main body of the apparatus and including an antenna surface for use in establishing near field communication. The cover includes a stacking portion in its upper section. The stacking portion is configured to receive a recording medium with an image thereon, the recording medium being discharged outside the main body of the apparatus. The antenna surface faces a region of the upper section of the cover downstream in a direction of discharging the recording medium. The antenna surface at least partially faces a region of the upper section of the cover outside the stacking portion in a direction perpendicular to the direction of discharging the recording medium. The communication portion is capable of communicating with another communication portion using near field communication. | 2015-11-26 |
20150338824 | DEVELOPING DEVICE, AND IMAGE FORMING APPARATUS AND PROCESS CARTRIDGE INCORPORATING SAME - A developing device includes a developer bearer to carry, by rotation, developer including toner and magnetic carrier to a developing range facing a latent image bearer; a casing including a developer container and an opening to expose a part of the developer bearer disposed in the casing; an opposing face of the casing including a conductive material and opposing to a surface of the developer bearer downstream from the developing range in a direction of rotation of the developer bearer; a developing bias source to apply a developing bias to the developer bearer; and an insulation layer disposed on the opposing face of the casing. The opposing face is disposed across, from the developer bearer, a casing gap sized to allow the developer borne on the developer bearer to contact the opposing face. | 2015-11-26 |
20150338825 | Drive Coupler - A replaceable unit for an image forming device according to one example embodiment includes a housing having a reservoir for storing toner. The replaceable unit includes a rotatable drive coupler and a rotatable shaft that has a cross pin on an axial end of the shaft, generally orthogonal to the shaft. At least a portion of the drive coupler is exposed on an exterior of the housing and unobstructed to receive rotational force when the replaceable unit is installed in the image forming device. A pocket is formed in a first axial side of the drive coupler. The axial end of the shaft and the cross pin are removably positioned in the pocket such that upon rotating the drive coupler in an operative direction rotational force is transferred from surfaces of the drive coupler forming the pocket to the cross pin causing the shaft to rotate with the drive coupler. | 2015-11-26 |
