A process cartridge mountable in and dismountable from an image forming apparatus, the process cartridge comprising:
- a frame;
- a photosensitive member rotatably supported by the frame;
- a storing portion provided on a mounting surface of the frame and configured to store information on the process cartridge;
- a projection projecting outwardly of the mounting surface in a direction normal to the mounting surface;
- and
- an electrical contact portion mounted on the projection and electrically connected to the storing portion,
- wherein the storing portion is disposed different from the projection in an axial direction of the photosensitive member, and
- wherein a size of the storing portion is larger than a size of the electrical contact portion when viewed in the direction normal to the mounting surface.
An image forming apparatus comprising:
- a main assembly;
- a process cartridge mountable in and dismountable from the main assembly of the image forming apparatus, the process cartridge including:
- a frame,
- a photosensitive member rotatably supported by the frame,
- a storing portion provided on a mounting surface of the frame and configured to store information on the process cartridge,
- a projection projecting outwardly of the mounting surface in a direction normal to the mounting surface, and
- two electrical contact portions mounted on the projection and electrically connected to the storing portion,
- a transfer portion configured to transfer an image, formed using the process cartridge, onto a sheet;
- a connector including two main assembly-side electrical contact portions contacting the two electrical contact portions of the process cartridge;
- moving means configured to move the connector;
- and
- a guiding member configured to guide movement of the connector,
- wherein the connector is moved with mounting of the process cartridge to establish contact of the two electrical contact portions of the process cartridge with the two main assembly-side electrical contact portions of the main assembly,
- wherein the storing portion is disposed at a position different from the projection in an axial direction of the photosensitive member, and
- wherein a size of the storing portion is larger than a size of the electrical contact portion when viewed in the direction normal to the mounting surface.
A process cartridge mountable in and dismountable from an image forming apparatus, the process cartridge comprising:
- a frame;
- a developing member rotatably supported by the frame;
- a storing portion provided on a mounting surface of the frame and configured to store information on the process cartridge;
- a projection projecting outwardly of the mounting surface in a direction normal to the mounting surface;
- and
- an electrical contact portion mounted on the projection and electrically connected to the storing portion,
- wherein the storing portion is disposed at a position different from the projection in an axial direction of the photosensitive member, and
- wherein a size of the storing portion is larger than a size of the electrical contact portion when viewed in the direction normal to the mounting surface.
