Process cartridge and image forming apparatus
A process cartridge mountable in and dismountable from an image forming apparatus includes a 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.
1. 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 and configured to store information on the process cartridge;
a projection formed integrally with the mounting surface and projecting outward in a direction perpendicular 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 than the projection in an axial direction of the photosensitive member, and
wherein the projection includes a positioning portion protruding from the electrical contact portion in the direction perpendicular to the mounting surface, with the positioning portion being a separate member from the electrical contact portion.
2. A process cartridge according to claim 1 , further comprising a flexible substrate,
wherein the electrical contact portion and the storing portion are disposed on the flexible substrate.
3. A process cartridge according to claim 1 , 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.
4. A process cartridge according to claim 1 , wherein the projection is provided with a supporting surface supporting the electrical contact portion, and
wherein a distance between the mounting surface and the supporting surface with respect to the direction perpendicular to the mounting surface is longer than a distance between the supporting surface and a surface of the electrical contact portion.
5. An image forming apparatus comprising:
a process cartridge according to claim 1 ;
a transfer portion configured to transfer an image, formed using the process cartridge, onto a sheet;
a fixing portion configured to fix the image, transferred by the transfer portion, on the sheet; and
a connector electrically contacting the electrical contact portion, a position of the connector to the process cartridge being determined by the connector being positioned to the positioning portion.
6. 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 and configured to store information on the process cartridge;
a projection formed integrally with the mounting surface and projecting outward in a direction perpendicular 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 developing member, and
wherein the projection includes a positioning portion protruding from the electrical contact portion in the direction perpendicular to the mounting surface, with the positioning portion being a separate member from the electrical contact portion.
7. A process cartridge according to claim 6 , further comprising a flexible substrate,
wherein the electrical contact portion and the storing portion are disposed on the flexible substrate.
8. A process cartridge according to claim 6 , 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.
9. A process cartridge according to claim 8 , wherein the projection is provided with a supporting surface supporting the electrical contact portion, and
wherein a distance between the mounting surface and the supporting surface with respect to the direction perpendicular to the mounting surface is longer than a distance between the supporting surface and a surface of the electrical contact portion.
10. An image forming apparatus comprising:
a process cartridge according to claim 6 ;
a transfer portion configured to transfer an image, formed using the process cartridge, onto a sheet;
a fixing portion configured to fix the image, transferred by the transfer portion, on the sheet; and
a connector electrically contacting the electrical contact portion, a position of the connector to the process cartridge being determined by the connector being positioned to the positioning portion.
