Abstract:
1. An image forming apparatus comprising: an image bearing member on which an electrostatic image is formed; a color developing unit having a color developing agent bearing member configured to bear a color developing agent containing a color toner, the color developing unit configured to develop the electrostatic image formed on the image bearing member at a development position; a transparence developing unit having a transparent developing agent bearing member configured to bear a transparent developing agent containing a transparent toner, the transparence developing unit configured to develop the electrostatic image formed on the image bearing member at the development position; a rotary member configured to hold the color developing unit and the transparence developing unit and to rotationally move the held color developing unit and the held transparence developing unit toward the development position; a driving device configured to rotationally drive the rotary member; a toner accumulation portion arranged below the rotary member in a gravity direction, falling toner accumulating therein; and a controller configured to control the driving device such that the rotary member is in a standby state at a reference position before image formation; wherein, when the rotary member is located at the reference position, the color developing agent bearing member is located in a region extending from a position of the transparent developing agent bearing member toward a downstream side of a rotation direction of the rotary member to a lowermost point in the gravity direction of the rotary member.
