Claims17
An electrophotographic photosensitive member comprising a photosensitive layer on a conductive support, wherein said photosensitive layer contains the following compound, said compound having structures (A) and (B) together in its structural formula:
- (A) A disubstituted aminoaryl group represented by Formula (I):
- ##STR62## wherein R.sub.1 and R.sub.2 each is an alkyl group, aryl group or aralkyl group that may have a substituent, or a residual group necessary to form a ring of 5 or 6 members by the combination of R.sub.1 and R.sub.2, and Ar.sub.1 is an arylene group that may have a substituent;
- (B) A (di) sulfide structure selected from the group consisting of (1) to (4):
- (1) A chain sulfide structure represented by Formula (II):
- Formula (II)
- --S--R.sub.3
- wherein R.sub.3 is an alkyl group or aralkyl group that may have a substituent,
- (2) A chain disulfide structure represented by Formula (III):
- Formula (III)
- --S--S--R.sub.4
- wherein R.sub.4 is an alkyl group or aryl group or aralkyl group that may have a substituent,
- (3) A chain sulfide structure represented by Formula (IV) and a chain sulfide structure represented by:
- Formula (V):
- Formula (IV)
- --S--R.sub.5
- wherein R.sub.5 is an aryl group that may have a substituent,
- Formula (V)
- --S--R.sub.6
- wherein R.sub.6 is an alkyl group, aryl group or aralkyl group that may have a substituent,
- (4) A cyclic sulfide structure or cyclic disulfide structure which is a 6- or 7-membered ring containing two or more sulfur atoms.
An electrophotographic photosensitive member comprising a photosensitive layer on a conductive support, wherein said photosensitive layer contains a thioether compound represented by Formula (VI):
- ##STR63## wherein R.sub.1 and R.sub.2 each is an alkyl group, aralkyl group or aryl group that may have a substituent, or a residual group necessary to form a ring of 5 to 6 members by the combination of R.sub.1 with R.sub.2 ;
- Ar.sub.2 is an arylene group or divalent heterocylic group that may have a substituent;
- n is an integer of 0 of 1;
- X is S--R.sub.7 or ##STR64## Y is S--R.sub.9, an alkyl group, aralkyl group or aryl group that may have a substituent, or X and Y is a residual group necessary to form a thioether ring by the combination of X with Y;
- and R.sub.7, R8 and R.sub.9 each is an alkyl group, aralkyl group or aryl group that may have a substituent.
