摘要： An electrophotographic system is constituted by an electrophotographic photosensitive member, a charger for charging the photosensitive member to a potential, and an illuminator for illuminating the charged photosensitive member with a light beam to form an electrostatic image thereon. The electrophotographic photosensitive member has a potential-exposure energy characteristic providing an induction energy and a gamma valve varying depending on an electric field intensity induced by the charged potential. The electrophotographic system further includes a controller for controlling the charged potential on the photosensitive member corresponding to resolution and gradation data of an original, so as to optimally reproduce the resolution and gradation, as desired, of the original.

摘要： An electrophotographic photosensitive member is constituted by disposing a photosensitive layer including a charge generation layer and a charge transport layer on an electroconductive support. The charge transport layer has a thickness of at most 12 .mu.m and is formed by dispersing therein particles having a particle size of 1-3 .mu.m at a density of 1.times.10.sup.4 -2.times.10.sup.5 particles/mm.sup.2. The charge transport layer and the particles described above provides a difference in refractive index of at least 0.10. The photosensitive member is effective in providing good images free from black spots and interference fringes and with a good gradation-reproducing characteristic when used as a structural member of a process cartridge and an image forming apparatus.
