METHOD AND SYSTEM OF EVALUATING SURFACE ROUGHNESS OF IMAGE FORMING APPARATUS COMPONENT, AND METHOD AND SYSTEM FOR CUTTING

摘要

PROBLEM TO BE SOLVED: To highly sensitively and correctly know a local change or modification of a surface to be measured in measuring surface roughness of an image forming apparatus component such as a substratum for use of an electrophotographic photoreceptor.;SOLUTION: A profile curve defined in JIS B0601 is calculated on a surface condition of the image forming apparatus component such as the electrophotographic photoreceptor substratum. Multiple resolution analysis such as wavelet transformation of a positional data row in the surface roughness direction at equal intervals on the profile curve is performed, and the surface roughness condition is evaluated based on the results.;COPYRIGHT: (C)2008,JPO&INPIT
