Patent ID: 7890013

Claim:
An image forming apparatus comprising: an apparatus body having a unit receiving section, and a photosensitive-member unit retaining a plurality of photosensitive members, the photosensitive-member unit configured to be slidable with respect to the apparatus body between a first position at which the photosensitive-member unit is received by the unit receiving section and a second position at which the photosensitive-member unit is away from the unit receiving section, and wherein the apparatus body comprises side wall portions opposing each other with the unit receiving section sandwiched therebetween, a plurality of first apparatus-body-side electrode members that is provided on at least one of the side wall portions in correspondence with the plurality of photosensitive members, the plurality of first apparatus-body-side electrode members arranged in line along a sliding direction of the photosensitive-member unit, and a plurality of second apparatus-body-side electrode members that is provided on at least one of the side wall portions in correspondence with the plurality of the photosensitive members, the plurality of second apparatus-body-side electrode members arranged in line along the sliding direction of the photosensitive-member unit and below the plurality of first apparatus-body-side electrode members; the photosensitive-member unit comprises a plurality of first unit-side electrode members corresponding to the plurality of first apparatus-body-side electrode members, respectively, and connected to the respective first apparatus-body-side electrode members when the photosensitive-member unit is mounted in the unit receiving section, and a plurality of second unit-side electrode members corresponding to the plurality of second apparatus-body-side electrode members, respectively, and connected to the respective second apparatus-body-side electrode members when the photosensitive-member unit is mounted in the unit receiving section; the plurality of first-unit-side electrode members is configured so as to pass through above the plurality of first-apparatus-body-side electrode members when the photosensitive-member unit moves from the second position to the first position; and the plurality of second-unit-side electrode members is configured so as to pass through between the plurality of first-apparatus-body-side electrode members and the plurality of second apparatus-body-side electrode members when the photosensitive-member unit moves from the second position to the first position.
