Claim:
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 an electric field formed between said transfer member and said stretching member to transfer the toner image onto the recording material by forming a first electric field in a predetermined direction when a first toner image passes through the 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, and the second toner image passes through the transfer portion, said controller forms a second electric field in the predetermined direction having an absolute value which is smaller than an absolute value of the first electric field for transferring the first toner image onto the recording material, and said fur brush electrostatically cleans said transfer member.
