PURPOSE:To obtain an electrophotographic sensitive body superior in electrostatic chargeability characteristics, sensitivity, durability, etc., by incorporating a specified bisazo compd. in a photosensitive layer in combination with one selected from carrier transfer substances in a wide range. CONSTITUTION:A photosensitive body superior in heat and humidity resistance, etc. is obtained by forming a photosensitive layer obtained by incorporating a compd. as a carrier generating substance together with a carrier transfer substance in one photosensitive layer or especially forming a laminate type photosensitive layer composed of a carrier transfer layer and a carrier generating layer contg. said compd. represented by formula I in which Y1, Y2 are each H, halogen, CN, alkyl, or alkoxy; A is one of groups represented by formulae II- V; Z is an atomic group necessary to form an optionally substd. aromatic C ring or aromatic hetero ring; Q is optionally substd. carbamoyl or sulfamoyl; R1 is H, optionally substd. alkyl or amino or carbamoyl, COOH, its ester, or CN, and R2, R3 are each optionally substd. alkyl or aralkyl or aryl. |
