Image forming apparatus wherein, when a rotary member is located at a reference position, a color developing device is located in a region extending from a position of a transparent developing device toward a downstream side of a rotation direction of the rotary member to a lowermost point in the gravity direction of the rotary member

摘要

An image forming apparatus includes color developing units for development with color developing agents, a transparence developing unit for development with a transparent developing agent, a rotary member which holds and rotationally moves the color and transparence developing units toward a development position, a driving device which rotationally drives the rotary member, a toner accumulation portion arranged below the rotary member in a gravity direction, falling toner accumulating therein, and a controller capable of starting image formation after the rotary member is moved to a reference position for rotation start. When the rotary member is located at the reference position, stop control thereof is performed such that at least one color developing unit is located in a region arranged downstream of the transparence developing unit and upstream of a lowermost portion of the rotary member in the gravity direction, with reference to the rotation direction of the rotary member.
