PROCESS CARTRIDGE AND IMAGE FORMING APPARATUS

摘要

A process cartridge includes a drum unit configured to rotatably hold a photosensitive drum, a developing unit that is assembled in such a manner as to be rotatable relative to the drum unit and includes a developing roller, gap maintaining members provided to the photosensitive drum or the developing roller on both end portions of the photosensitive drum in an axial direction, and urging members configured to bias the developing unit toward the drum unit. The urging members are respectively disposed on outer sides of the gap maintaining members disposed at both end portions in the axial direction. The drum unit or the developing unit includes an electric contact portion configured to come into contact with an electric contact of an image forming apparatus when the process cartridge is attached to the image forming apparatus, the electric contact portion being disposed between the gap maintaining members in the axial direction.

主权项

1. A process cartridge detachably attached to an image forming apparatus, the process cartridge comprising:
a drum unit configured to rotatably hold a photosensitive drum.; a developing unit that is assembled in such a manner as to be rotatable relative to the drum unit and includes a developing roller configured to supply a developer to the photosensitive drum; gap maintaining members provided to the photosensitive drum or the developing roller on both end portions of the photosensitive drum in an axial direction, the gap maintaining members holding the developing roller while being apart from the photosensitive drum with a gap in between; and urging members configured to bias the developing unit toward the drum unit in such a direction that the developing roller comes into contact with the photosensitive drum, wherein the urging members are respectively disposed on outer sides of the gap maintaining members disposed at both end portions in the axial direction, and wherein the drum unit or the developing unit includes an electric contact portion configured to come into contact with an electric contact of the image forming apparatus when the process cartridge is attached to the image forming apparatus, the electric contact portion being disposed between the gap maintaining members in the axial direction.
