摘要： The invention concerns a screen photosensitive member, and an electrophotographic method using such screen photosensitive member, and relates to improvement in the screen constructed with an electrically conductive member, a photoconductive layer provided on the electrically conductive member, and a surface insulative layer constituting the screen surface at the side opposite to at least a modulating corona source. More particularly, the screen according to the present invention is further provided, at the side of the modulating corona source, with a potential holding layer which holds thereon corona ions applied to it and maintains the surface of the screen at the side of the modulating corona source at a predetermined potential.By the use of the screen of the present invention, it becomes possible to improve the potential of a latent image formed on the screen and, moreover, to effect ion modulation repeatedly from one and the same latent image formed on the screen owing to the capability of the potential holding layer to maintain the potential on one surface side of the screen at a predetermined level and to absorb due to the characteristic of this potential holding layer, excessive charge for the modulation as applied to the screen.
