Patent ID: 7720405

Claim:
An image forming apparatus comprising an apparatus body, and a photosensitive-member unit slidably attached to and detached from the apparatus body and retaining a plurality of photosensitive members, wherein the apparatus body comprises side wall portions opposing each other with a unit receiving section for removably receiving the photosensitive-member unit sandwiched therebetween, and a plurality of apparatus-body-side electrode members provided on the side wall portions, corresponding to the plurality of photosensitive members, and each urged inward in an opposing direction of the side wall portions, and the photosensitive-member unit comprises a plurality of unit-side electrode members corresponding to the plurality of apparatus-body-side electrode members, respectively, connected to the respective apparatus-body-side electrode members in a state where the photosensitive-member unit is mounted in the unit receiving section, and protruding outward in the opposite direction, and a guide path comprising a flat surface formed in a flat shape so that each of the apparatus-body-side electrode members slidably contacts to the flat surface during attachment and detachment of the photosensitive-member unit with respect to the unit receiving section, and that each of the apparatus-body-side electrode members slidably contacted maintains a constant inward and outward position in the opposed direction.
