PURPOSE:To obtain an electrophotographic sensitive body high in sensitivity and good in stability during repeated uses and good in photomemory by using titanium phthalocyanine compound as an electric charge generating material and a specified compound as an electric charge transfer material. CONSTITUTION:The titanium phthalocyanine compound to be used as the charge generating material formed on a conductive substrate is represented by formula I in which R1 is halogen, 0 atom, or alkoxy group; each of R2-R5 is H, halogen atom, alkyl, or alkoxy group; (j) is 1 or 2; each of (k), (l), (m), and (n) is an integer of 0-4; each of R6-R9 is H atom, alkyl, aralkyl, aryl, or alkoxy group, or each of (R6 and R7) and (R8 and R9) are residual group which may form a cyclic amino group together with each adjacent N atom, thus permitting the obtained electrophotographic sensitive body to be superior in exposure sensitivity characteristics, high in sensitivity in the long wavelength region of >=780nm, stable during repeated uses, and good in photomemory. |
