    摘要： An electrophotographic photosensitive member capable of forming images with less defects, such as ghost, while retaining a high photo-sensitivity, is provided. The photosensitive member includes a support and a photosensitive layer disposed on the support, wherein said photosensitive layer contains a phthalocyanine pigment and an azo calix[n]arene compound represented by the formula (1) below: wherein n denotes an integer of 4-8; a number (n) of R1 independently denote a hydrogen atom or an alkyl group capable of having a substituent and including at least one alkyl group capable of having a substituent; a number (2n) of R2 independently denote a hydrogen atom or an alkyl group capable of having a substituent; and a number (n) of Ar independently denote a monovalent group selected from an aromatic hydrocarbon ring group capable of having a substituent, a heterocyclic ring group capable of having a substituent, and a combination of these groups capable of having a substituent.

    摘要： 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:-0.2
