Title: Image forming device
Inventor: TSUDA SATOSHI
IPC: G03G15/045
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To provide, in the case, a photoreceptor having a High-γ characteristic is used in an electrophotographic process, the stability of the characteristic of the repeated electrification and the stability of residual potential by providing a preprocessing means which, before image formation, simultaneously emits light to the photoreceptor under the action of an electric field having the same polarity as the photoreceptor. SOLUTION: This device uses the photoreceptor 1 having a potential attenuation characteristic in which the potential VP of the uniformly electrified surface is suddenly attenuated having a certain amount of exposure, A0, as its boundary and is provided with the preprocessing means 2 which, before the image formation, emits light simultaneously to the photoreceptor 1 under the action of the electric field having the same polarity as the photoreceptor 1. Because the preprocessing means 2 cause the electric field having the same polarity as the photoreceptor 1 to act before the image formation, the electric field acts on the photoreceptor 1, as an external electric field, so that the photoreceptor 1 is brought into a state equivalent to an electrified state.  In this state, the preprocessing means 2 emits light simultaneously, therefore a large number of ion pairs by light excitation are generated and trap in the photoreceptor 1 is opened. As a result, the movement of charges which offsets the electrification potential occurs, and the residual potential of the photoreceptor 1 is removed.
