摘要： A cleaning device is disposed substantially vertical above a photosensitive drum for the purpose of constructing a compact electrophotographic printer. The cleaning device includes a housing that accommodates an auxiliary toner conveying part and a sheet-like resilient member. A cleaning brush is also disposed in the housing so that a gap of 1-3 mm is formed between the cleaning brush and the auxiliary toner conveying part and resilient member. During an image forming operation, toner accumulates between the cleaning blade and the cleaning brush and is conveyed upward through the gap between the cleaning brush and the auxiliary toner conveying part and resilient member. The toner drops onto the cleaning brush near the top thereof and is conveyed by the cleaning brush to a screw. The screw discharges the toner from the cleaning device.

摘要： According to an embodiment, there is provided a mechanism for electrification of a rotating body used in an image forming apparatus. In the mechanism, compression of an elastically-deformable pressing member brings a portion of a cloth-like or sheet-like conductive member into contact with an electrification object and presses the rest of the conductive member against a conductive contact member, which is any one of the rotating body, a rotating shaft that rotates together with the rotating body, and a shaft that rotatably supports the rotating body. A connecting between the electrification object and the contact member is achieved via the conductive member.

摘要： A developing device includes a developer bearer, an end seal, and an inlet seal. The end seal is disposed in contact with a circumferential surface of each end of the developer bearer in a longitudinal direction of the developer bearer. The inlet seal includes a center portion in the longitudinal direction disposed in contact with the developer bearer and each end in the longitudinal direction disposed in contact with the end seal. The end seal includes a cutout portion at a side closer to the center portion in the longitudinal direction and at an upstream side in a direction of rotation of the developer bearer. The inlet seal covers an edge of the cutout portion in the longitudinal direction.

摘要： A developing device is provided with a developer accommodating vessel accommodating developer having as primary components a nonmagnetic toner and magnetic particles referred to as a carrier. The carrier is composed of a magnetic material as a core material that is uniformly covered with an insulating synthetic resin. The toner is mixed with the carrier at a weight ratio to the overall weight of the developer of 3-10%. The carrier has an average particle size of 65 μm or less and a saturation magnetization of at least 70 emu/g. The developing device includes a developing roller and a sleeve roller that rotates about the developing roller. The surface of the sleeve roller is processed with metal shot to achieve a surface roughness of 0.45-1.08 times the average particle size of the carrier, or more specifically a roughness Rz of about 30 μm.
