Claim:
An image forming apparatus, comprising: a main unit; and a process cartridge that includes: an image holding member which rotates about a rotation axis; a developing device which develops a latent image on the image holding member; and a supporting member which is formed with a side face spreading in a direction of the rotation axis and supports the image holding member and the developing device, and a cartridge side connector on the side face of the supporting member, wherein the process cartridge is moved in the direction of the rotation axis so as to be attached and detached to and from the main unit, the main unit includes: a main unit connector which is arranged at a position adjacent to a side face of the supporting member of the process cartridge, which is electrically connected to the cartridge side connector when the process cartridge is attached to the main unit; and an exposure device which scans, in the direction of the rotation axis, by an exposure light beam, the image holding member included in the process cartridge attached to the main unit, and the main unit connector is arranged at a position not only overlapping an irradiation region of the exposure light beam on the image holding member in an irradiation direction of the exposure light beam, but also avoiding, with respect to the direction of the rotation axis, an area where the exposure light beam passes through.
