An electrostatic latent image can be obtained by first charging an i-type photoreceptor in a dark place by, for example, TID discharge, and then selectively discharging the charge only in the exposed area. This is one of the image forming methods in which an image is visualized using a developing means using 1-ner or the like. Like this
The basic characteristics required of a photoreceptor used in electrophotography are 1) to be charged to an appropriate potential when placed in a dark place, 2) to have little discharge of charge in a dark place, 3
) Promptly discharging charges using light heat 01. However, the reality is that conventional photoconductive materials do not necessarily satisfy these requirements.
