Patent ID: 8428486

Claim:
An image forming apparatus comprising: an apparatus main body including an apparatus main body contact; a plurality of photosensitive units which include photosensitive members, respectively, and are provided in parallel with each other and arranged in an arrangement direction at an interval, each of the photosensitive units including a unit contact; a process unit including the plurality of photosensitive units therein, and provided to be slidable with respect to the apparatus main body in the arrangement direction; and an electrode unit provided in the process unit and configured to electrically connect the photosensitive units to the apparatus main body, wherein each photosensitive unit includes a frame made of insulating resin, and the frame includes a protrusion which protrudes outward in a longitudinal direction of the photosensitive member, wherein the electrode unit includes: a plurality of unit-side electrode members which come into contact with the unit contacts of the photosensitive units, respectively; a relay electrode member which comes into contact with the respective unit-side electrode members to electrically connect the respective unit-side electrode members; and a body-side electrode member which comes into contact with the apparatus main body contact, wherein at least one of the unit-side electrode members includes a positioning plate orthogonal to a contact direction in which the at least one of the unit-side electrode members comes into contact with the relay electrode member, wherein the positioning plate is formed with a through hole which passes through the positioning plate in the contact direction, and wherein the protrusion is insertable into the through hole so that the at least one of the unit-side electrode members is positioned to the frame.
