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: EQU -0.2<W.sub.F.sup.CG -W.sub.F.sup. CT.ltoreq.0 (eV) The above steps is carried out while the photosensitive member rotates once at 1.5 seconds or less.
