Abstract
An image forming apparatus includes a cleaning unit removing toner remaining on an image bearing member after a toner image is transferred to an intermediate transfer member; a first storage unit which collects removed toner; a conveying unit which is driven by transmission of rotation of the image bearing member to convey toner in the first storage unit to a second storage unit; and a control unit which performs conveyance control, by driving the image bearing member to rotate during a non-image forming period, in which the conveying unit is caused to convey toner from the first storage unit to the second storage unit, wherein when an amount of toner in the first storage unit is equal to or larger than a threshold during an image forming period, the control unit executes the conveyance control during the non-image forming period to reduce the toner in the first storage unit.
