PURPOSE:To recover residual toner in an electrophotographic device without causing color mixture with simple constitution. CONSTITUTION:When the trailing edge part of the photoreceptor 5 of a photoreceptor drum 1 passes the position of a blade 8, a developing device 2 is raised in an inclined state, and then the drum 1 is rotated in a reverse direction to a process progressing direction, and the back surface of the trailing edge part of the photoreceptor 5 is allowed to abut on the blade 8 so that it may form an obtuse angle with the blade 8. By blowing air from a nozzle 10 for squeezing air to the trailing edge part of the photoreceptor 5, the residual toner at the trailing edge part of the photoreceptor 5 is allowed to flow along the blade 8, so that the residual toner is recovered. |
