Abstract

In the specific embodiments described herein, the charge drop resulting from fatigue in an electrophotographic process using an a-Se:H photosensitive member is reduced by a stabilization exposure carried out for one to three cycles prior to use of the member for image formation. Longer wavelength light may be used for the stabilization exposure and shorter wavelength light may be used for the imaging and discharge steps.
