PROBLEM TO BE SOLVED: To form an image of high image quality by solving the problem of being prone to the generation of a cleaning failure when small-particle toner is utilized with the target of high image quality. SOLUTION: In the device, a cleaning roll having bias voltage applied to separate electrified toner from a photoreceptor is provided on the upstream side of a cleaning blade, and the photoreceptor having a surface roughness Rz of 0.1 μm to 2.5 μm in an average of ten points is utilized. |
