<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus, having a simple configuration eliminating paper powder attaching to a surface of a photoreceptor and then dispersing the paper powder and at the same time, preventing deterioration in the photoreceptor which is not provided with a paper powder eliminating member. <P>SOLUTION: The image forming apparatus includes four photoreceptor drums 4, corresponding to respective colors and a drum wiper 30, which is only attached to the black photoreceptor drum 4K on the uppermost-stream side in the transport direction (direction, going from the front to the back) of a sheet S. In this case, all of the respective photoreceptor drums 4 are rotated in the forward direction, when a driving force in the forward direction is inputted in respective photoreceptor drums 4. Furthermore, only the black photoreceptor drum 4K is selectively rotated, in the reverse direction among the respective photoreceptor drums 4, when a driving force in the reverse direction is inputted to the respective photoreceptor drums 4. <P>COPYRIGHT: (C)2011,JPO&INPIT |
