Abstract
An image forming apparatus incudes an image bearing member, a developing member, a transferring member, an applying portion, a cleaning blade, and a controller. The controller executes an initial operation in which the image bearing member in a brand-new state is shifted to a printable state and an image forming operation. The controller controls the applying portion so as to apply a constant voltage to the transfer member in the initial operation different from that in the image forming operation, during a second period immediately before a first period for supplying the toner from the developing member to the image bearing member in the developing region, and controls so that the constant voltage in the second period has a normal charge polarity of the toner and becomes a voltage value which does not generate electrical discharge between the image bearing member and the transfer member.
