Organic photoreceptor for electrophotography |
摘要 |
An organic photoreceptor for electrophotography including a substrate which is electrically conductive; and an organic photosensitive layer which is formed on the substrate, which includes a photoconductive material, and which has a surface having a differential hardness corresponding to a 20 mu m or less change in width of a scratch formed on the surface for every 10 g change in vertical load during perpendicular loading with 10 g or more pressure on the surface when a test for evaluating differential hardness is performed by moving the photoreceptor to a predetermined position at a constant speed of 30 mm/minute under a load in a direction perpendicular to the surface through a conical indenter to make the scratch on the surface, which conical indenter is one of a sapphire or diamond conical indenter having a conical tip portion including an apex having a hemisphereical shape with a diameter of 0.01 mm and a conical angle of 90 DEG .
