CHARACTERISTIC EVALUATION METHOD AND CHARACTERISTIC EVALUATION SYSTEM FOR PHOTORECEPTOR AND EXPOSURE OPTICAL SYSTEM DESIGNING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new method for evaluating a photoconductive photoreceptor characteristic on which an electrostatic latent image is formed by an optical writing means through dot exposure.

SOLUTION: A beam profile on a beam exposure surface for dot exposure is specified as a beam profile function f. The profile of an electrostatic latent image formed on the photoreceptor by dot exposure by a beam that gives the beam profile function f is specified as an electrostatic latent image profile function g. A deterioration function h is obtained from de-convolution calculation using the specified beam profile function f and electrostatic latent image profile function g. Based on this deterioration function h, the photoreceptor characteristic is evaluated.
