PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of fast processing without contamination in a primary apparatus body by preventing toner from leaking from a cleaner housing by forcibly moving toner cloud in timing where a cleaner blade and a seal separate from a carrier surface. SOLUTION: The image forming apparatus which transfers a toner image formed on a photoreceptor drum surface with toner having a minus potential to a recording paper through an intermediate transfer belt 16 supplying a plus voltage and scrapes off remaining toner on an intermediate transfer belt surface by making the cleaner blade 21a and a seal member 21b contact and leave the intermediate transfer belt surface is characterized in that an electric field for attracting suspended toner into the cleaner housing 63 is produced and absorbed to an opposed member by applying a minus voltage to the opposed member 73 fixed to a seal support member 62 when the seal member leaves the belt surface.
