Abstract
An image forming apparatus includes an image bearing member; an electrostatic image forming unit; a developing device; an intermediary transfer member; a rotatable transfer member; a constant-voltage element; a power source; a cleaning device; an executing portion capable of executing a toner image collecting mode after jam clearance; and a controller for controlling the power source in an operation in a collecting mode so that a voltage of an identical polarity to a charge polarity of the toner is applied to the rotatable transfer member to transfer, onto the intermediary transfer member, the toner in an upstream-side end region of the toner image carried on the image bearing member with respect to the rotational direction of the image bearing member, and then a voltage of an opposite polarity to the charge polarity of the toner is applied to the rotatable transfer member.
