An electrophotographic apparatus is provided which has an electrophotographic photosensitive member, a charging member maintained in contact with the photosensitive member and charging the same by receiving a voltage, an exposure device, a developing device and a transfer device. The photosensitive member has a support, a charge generating layer on the support, and plural layers on the charge generating layer. The outermost surface layer of the plural layers has the largest relative dielectric constant. With the electrophotographic apparatus, good contrast between dark potential and light potential is maintained even after a prolonged use of the apparatus, and sufficient image density and image quality are obtained. Also a process cartridge adapted for use in the electrophotographic apparatus is provided.
