摘要： In an electrophotographic apparatus (e.g., a photocopier or laser printer), an electrophotographic photosensitive member (image-forming part) has a metal substrate roughened on its surface, a metal oxide-containing undercoat layer on the substrate, and an organic photosensitive layer over the undercoat. A coherent light source (e.g., laser) can cause interference fringes that degrade the printed image. Interference fringes are judged (or predicted) as follows: The surface reflectance is measured at intervals over the spectral width of the light source. The measured surface reflectance is corrected, using a mirror-surface conductive substrate as a reference, to obtain a reflectance of the photosensitive member. The reflectance is subjected to a discrete Fourier transformation, which generates a power spectrum, over the spectral width of the light source, from the reflectance as a function of the wavelength. Interference fringes are judged from the maximum peak value in the power spectrum, as compared to a predetermined value.
