摘要： A method of removing electrostatic charge for erasing an electrostatic latent image from an electrophotographic photosensitive device having a conductive layer overlain by a photoconductive layer which in turn is overlain by a transparent insulating layer. The method comprises a first step of uniformly charging the photosensitive device by a D.C. charger while subjecting the photosensitive device to an exposure over the whole area thereof; a second step of effecting a charging for adjustment of potential level so as to adjust the potential of the photosensitive device from the level obtained as a result of the charging in the first step to the aimed level; and a third step of exposing the whole area of the photosensitive device. With this method, it is possible to remove electrostatic charge almost perfectly to eliminate undersirable shift of the potential of the photosensitive device after the erasion.

摘要： An electrophotographic process employs an electrophotographic photosensitive member of a basic construction in which a photoconductive layer and a transparent insulator layer are sequentially laminated on the surface of a conductive supporter. The process in one preferred embodiment comprises a first step of providing a primary charge uniformly from the surface side of the transparent insulator layer, a second step of performing a secondary corona charging during an imagewise exposure by applying an a.c. voltage in which the firing angle of a negative half wave is controlled in phase to be within a phase angle corresponding to a lower voltage than the firing angle so that the positive discharge period may be longer than the negative one during one period, and a third step of forming an electrostatic latent image on the transparent insulator layer by applying a uniform exposure.

摘要： An electrophotographic photoreceptor has a photoconductive layer on a substrate. The photoconductive layer comprises a photoconductor and a water-soluble compound which reacts with free anion released from the photoconductor to produce an unsoluble salt and contains anion having smaller equivalent ionic conductance than that of the free anion.
