PURPOSE:To enhance sensitivity, potential stability, and durability by using a specified compound as an electric charge transfer material. CONSTITUTION:The electrophotographic sensitive body has a layer containing at least one of the compounds represented by formula I in which each of R1-R6 is optionally substituted alkyl, such aryl, or such aralkyl; each of l and m is independently 0 or 1; and n is integer of 2 or 3, and when all of R1-R4 is aryl, sensitivity and repetition characteristics are enhanced more than the other case, thus permitting sensitivity, potential stability, and durability to be improved. |
