Abstract
There are provided an electrophotographic photoreceptor which achieves excellent enduring characteristics and reduction in occurrence of image defects, and an image forming apparatus and an electrophotographic photoreceptor manufacturing apparatus. An electrophotographic photoreceptor includes a cylindrical base body; a charge injection blocking layer disposed on the cylindrical base body; a photoconductive layer disposed on the charge injection blocking layer; and a surface layer disposed on the photoconductive layer, the surface layer having a surface roughness defined as: texture aspect ratio Str>0.67.
Claims16
An electrophotographic photoreceptor, comprising:
- a cylindrical base body;
- a charge injection blocking layer disposed on the cylindrical base body;
- a photoconductive layer disposed on the charge injection blocking layer;
- and
- a surface layer disposed on the photoconductive layer, the surface layer having a surface roughness defined as:
- texture aspect ratio Str≥0.67.
An electrophotographic photoreceptor manufacturing apparatus, comprising:
- a surface roughening section which roughens an outer surface of a cylindrical base body;
- a charge injection blocking layer-forming section which forms a charge injection blocking layer on the outer surface of the cylindrical base body;
- a photoconductive layer-forming section which forms a photoconductive layer on the charge injection blocking layer;
- and
- a surface layer-forming section which forms, on the photoconductive layer, a surface layer having a roughened outer surface having a surface roughness which is defined as:
- texture aspect ratio Str≥0.67.
