Title:
ELECTROPHOTOGRAPHIC PHOTOCONDUCTOR DRUM, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2021173806
Kind Code:
A
Abstract:
To provide an electrophotographic photoconductor drum that achieves both reduction in torque of the electrophotographic photoconductor drum during cleaning and improvement in transferability of an image.SOLUTION: An electrophotographic photoconductor drum has a support and a photosensitive layer provided on the support and is provided, on an outer surface, with at least two structural groups having periods with different appearances. Of the two structural groups in the electrophotographic photoconductor drum, when the group configured of a structure having a period with smaller appearance is a first structural group, and the group configured of a structure having a period with larger appearance is a second structural group, the height of the first structural group is lower than the height of the second structural group.SELECTED DRAWING: Figure 7
