Abstract
The present invention relates to a photosensitive member containing a specific hydrazone compound or a specific azine compound for a charge transporting agent, which is improved in a sensitivity, chargeability, resistivity for repeated use and stability.
Claims8
A photosensitive member containing a hydrazone and/or an azine compound represented by one of the following general formulaes (I) and (II):
- ##STR16## wherein R.sub.1 and R.sub.2 independently are any of alkyl group, aralkyl group, aryl group and heterocyclic group, where each group may have a substituent;
- R.sub.1 and R.sub.2 may combinedly form a ring;
- R.sub.3 is any of a hydrogen atom, alkyl group, aralkyl group, aryl group and heterocyclic group, where the aralkyl group, aryl group and heterocyclic group may have a substituent;
- X is represented by the formula:
- ##STR17## wherein R.sub.4 and R.sub.5 independently are any of a hydrogen atom, halogen atom, alkyl group, alkoxy group, aralkyl group, aryl group, aryloxy group, and aralkyloxy group, where each group may have a substituent;
- l and n independently are an integer 0 through 6;
- m is an integer 0 through 2;
- and Z is a heterocyclic group forming a ring containing a nitrogen atom, which may have a substituent;
- ##STR18## Wherein R.sub.3, X and Z are the same as in (I);
- R.sub.6 and R.sub.7 independently are any of a hydrogen atom, alkyl group, aryl group and heterocyclic group, where each group may have a substituent;
- and R.sub.6 and R.sub.7 may combinedly form a ring and further comprising a photoconductive material.
