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 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.

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. 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; and

a fixing portion configured to fix the image, transferred by the transfer portion, on the sheet.

4. 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.

5. An image forming apparatus according to claim 4 , wherein in the process cartridge at a periphery of the two electrical contact portions, a rib is provided extending in a direction in which the two electrical contact portions are adjacent to each other, and

wherein the connector is positioned relative to the process cartridge by contact thereof with the rib of the process cartridge.

6. An image forming apparatus according to claim 5 , wherein in the process cartridge the two electrical contact portions and the storing portion are electrically connected to each other by electrical wires, and

wherein the electrical wires pass through a space between the guiding member and the mounting surface.

7. An image forming apparatus according to claim 5 , wherein the process cartridge includes a flexible substrate on which the two electrical contact portions and the storing portion are disposed, and

wherein the flexible substrate passes through a space between the guiding member and the mounting surface.

8. 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.

9. A process cartridge according to claim 8 , further comprising a flexible substrate,

wherein the electrical contact portion and the storing portion are disposed on the flexible substrate.
