Patent ID: 7238457

Claim:
An electrophotographic photoreceptor comprising a support, and provided thereon, an interlayer comprising inorganic particle and a photosensitive layer, wherein the photosensitive layer contains a mixture of two or more compounds each of which is represented by Formula (1) having a specific number n different each other, X—(CTM-group) n—Y (1) wherein CTM-group is a charge transfer group; X and Y are each a hydrogen atom, a halogen atom or a mono-valent organic group; and n is an integer of 0 to 10, provided that n is not 0 when both X and Y are a hydrogen atom or a halogen atom, and (Rp+Rs) is not more than 99%, wherein Rp is a content of a compound represented by Formula (1) which has a first specific number n and a maximum content in the mixture, and Rs is a content of a component represented by Formula (1) which has a second specific number n and a content next to the maximum content based on weight in percent.
