Abstract
Function of polarized space charge should not be neglected during the formation of a latent image in an electrophotographic process using a photoreceptor overcoated with an insulating film. There, the persistency of the polarized space charge plays an important role. To make the understanding of the role, in the present paper, a process utilizing effectively the polarized space charge produced in a photoconductive layer when such a photoreceptor is used with corona charge has been analysed and the quantitative description has been presented. From this analysis, it has been found that various types of latent image will be produced. Experiments to confirm the prediction have been made. It has been shown that the quantitative description in this paper is probable from the comparison between the prediction and the experiment.
