<P>PROBLEM TO BE SOLVED: To improve circularity of a lubricant of a highly durable electrophotographic photoreceptor having a surface layer, thereby extending the lifetime of the electrophotographic photoreceptor and an image forming device, and reducing print cost. <P>SOLUTION: In the electrophotographic photoreceptor having a photosensitive layer and a surface layer on a conductive support, multiple resolution analysis is performed where a one-dimensional data array obtained by measuring the concave/convex shape on the electrophotographic photoreceptor surface using a surface roughness/contour shape measuring machine is wavelet-transformed to be separated into six high to low frequency components. The multiple resolution analysis is additionally performed to obtain another six high to low frequency components. As for the arithmetic average roughness of each of the twelve frequency components, WRa(HMH) is 0.002 to 0.004 μm and WRa(LHL) is 0.002 to 0.010 μm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
