Patent ID: 8693917

Claim:
An image forming apparatus comprising: an apparatus main body having an opening at a front side; a plurality of photosensitive members; a plurality of developing sections each provided for a corresponding one of the plurality of photosensitive members; a developing-section supporting member configured to hold the plurality of developing sections and to be pulled out through the opening from a mount position inside the apparatus main body to a replacement position outside the apparatus main body where the plurality of developing sections is configured to be mounted and dismounted; a photosensitive-member supporting member configured to hold the plurality of photosensitive members and to be pulled out through the opening from an internal position inside the apparatus main body to an external position outside the apparatus main body; a belt provided to confront the plurality of photosensitive members; a cover configured to move between a closed position at which the opening is closed and an open position at which the opening is opened; a developing-section displacement mechanism configured to support the developing-section supporting member and to displace the developing-section supporting member between: a first adjacent position at which the developing-section supporting member is adjacent to the plurality of photosensitive members with respect to a direction perpendicular to a pulling direction of the developing-section supporting member; and a first separated position at which the developing-section supporting member is separated from the plurality of photosensitive members with respect to the direction perpendicular to the pulling direction of the developing-section supporting member; a photosensitive-member displacement mechanism configured to support the photosensitive-member supporting member and to displace the photosensitive-member supporting member between: a second adjacent position at which the photosensitive-member supporting member is adjacent to the belt with respect to a direction perpendicular to a pulling direction of the photosensitive-member supporting member; and a second separated position at which the photosensitive-member supporting member is separated from the belt with respect to the direction perpendicular to the pulling direction of the photosensitive-member supporting member; and an interlocking mechanism configured to interlock the developing-section displacement mechanism and the photosensitive-member displacement mechanism with the cover, and to displace the developing-section supporting member and the photosensitive-member supporting member from the respective adjacent positions to the respective separated positions when the cover moves from the closed position to the open position.
