ABSTRACT:
An image forming process is carried out through the steps of electrostatically charging a cylindrical electrophotographic photosensitive member, forming an electrostatic latent image by image exposure, developing the latent image and transferring the developed image to a transfer member. The photosensitive member is comprised of a conductive support and a photosensitive layer which contains oxytitanium phthalocyanine as a charge-generating material and a charge-transporting material. The charge-generating material and the charge-transporting material have a work function (W.sub.F.sup.CG) and a work function (W.sub.F.sup.CT), respectively. Those work functions satisfies the following relationship:
