    • PURPOSE: A dihydrazone-based charge transfer compound, an organic photoreceptor containing the compound, an electronograph image formation device using the organic photoreceptor and its method are provided, to obtain a high photosensitivity, a low residual potential and high stabilities to cycle test, crystallization and bending and stretching of an organic photoreceptor. CONSTITUTION: The charge transfer compound is represented by the formula 1, wherein n is 0 or 1; X is an N,N-disubstituted arylamine group; Ar is an aryl group or a hetero ring having at least one halogen, nitrogen, oxygen or sulfur atom as a ring member; A is a first linking group which is represented by -(CH2)p- and is linear or branched (wherein p is an integer of 3-20, at least one methylene group is optionally substituted with O, S, carbonyl, urethane, ester, NR21, CHR22 or CR23R24, and R21, R22, R23 and R24 are independently H, OH, thiol, amine, alkyl, alkaryl, aryl or a part of a ring); B is a second linking group represented by -Q-Z-Q'- (wherein Q and Q are independently O, S or NR1; and Z comprises an aryl group if Q or Q' is NR1 or Q is O and Q' is S, and Z is a polycyclic conjugated group or -Y-W-Y'- if Q and Q' and S or Q and Q' are O, wherein Y and Y' independently are an aryl group, W is CR2R3, R1 is H or an alkyl or aryl group, R2 is H or an alkyl or aryl group, and R3 is an alkyl or aryl group or forms a ring together with R2). The organic photoreceptor comprises the charge transfer compound of the formula 1; a charge generation compound; and a conductive supporter.
