Abstract:
1. An image forming apparatus comprising: a belt member; toner image forming means for forming a toner image on said belt member; a stretching member for stretching said belt member at an inside of said belt member; a transfer member, pressed against said stretching member through said belt member, for forming a transfer portion for transferring a first toner image onto a recording material; a fur brush for electrostatically cleaning said transfer member; a controller for controlling a voltage for applying to said stretching member to transfer the first toner image onto the recording material by applying a first voltage of a predetermined polarity to said stretching member when the first toner image passes through said transfer portion; and an executing portion for executing an ejecting operation for forming by said toner image forming means, on said belt member, a second toner image in the form of a band which is not transferred onto the recording material, wherein when said executing portion executes the ejecting operation, said stretching member is supplied with a second voltage which has the predetermined polarity and which has an absolute value smaller than an absolute value of the first voltage for transferring the first toner image onto the recording material, and subsequently, said fur brush electrostatically cleans said transfer member.
