Title:
PHOTORECEPTOR DRUM, IMAGE FORMING APPARATUS, AND REGENERATION METHOD FOR PHOTORECEPTOR DRUM
Document Type and Number:
Japanese Patent JP2021039194
Kind Code:
A
Abstract:
To provide a photoreceptor drum in which good characteristics can be obtained even after polishing, an image forming apparatus including the photoreceptor drum, and a regeneration method for a photoreceptor drum.SOLUTION: A surface of a protective layer 4 of a photoreceptor drum 1 is polished by a polishing device 100 having aggregated abrasive grains. The arithmetic average roughness Ra on the surface of the protective layer 4 is less than 0.03 μm, and the arithmetic average waviness Wa is 0.05 μm or more. In this way, the surface roughness is reduced at a relatively micro level and a wavy shape of the surface is maintained at a relatively macro level, and thereby good characteristics can be obtained even for the photoreceptor drum after the polishing.SELECTED DRAWING: Figure 4
