    • An electrophotographic photoreceptor comprising a support, an interlayer containing inorganic particle and a photosensitive layer is disclosed. The photosensitive layer contains a mixture of compounds represented by Formula (1) having different n and (Rp+Rs) is not more than 99%, wherein Rp is a ratio of a component having the maximum content in the mixture and Rs is a ratio of a component having the content next to the maximum content in percent. X—(CTM-group)n—Y   (1) In the formula, 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 from 0 to 10, provided that n is an integer of from 1 to 10 when both X and Y are hydrogen atom or a halogen atom. A processing cartridge comprising the electrophotographic photoreceptor is also disclosed.
