ABSTRACT:
An image forming apparatus includes a toner image forming means for forming a toner image on a belt member, a stretching member that stretches the inside of the belt member, a transfer member, a fur brush, and a controller. The transfer member presses against the stretching member through the belt member, forming a transfer portion for transferring a first toner image onto a recording material. The controller applies a first voltage of a predetermined polarity to the stretching member to transfer the first tone image onto the recording material. During an ejecting operation, the toner image forming member forms a second toner image which is not transferred to the recording material, and the stretching member is supplied with a second voltage that has the predetermined polarity and an absolute value smaller that an absolute value of the first voltage, and subsequently the fur brush electrostatically cleans the transfer member.
