PURPOSE: To provide the photosensitive body having a particularly excellent electrophotographic sensitive at the time of positive electrostatic charge by using a pyrylium dye, electrically insulating polymer and specific compd. as essential components. n CONSTITUTION: This photosensitive body contains the pyrylium dye, the electrically insulating polymer and the compd. expressed by formula I on a conductive base body. In the formula I, R 1 and R 2 denote a hydrogen atom, amino group; R 3 and R 4 denote a hydrogen atom, alkoxy group, etc.; Ar denotes a substd. or unsubstd. monocyclic arom. hydrocarbon group, substd. or unsubstd. non- condensed polycylic arom. hydrocarbon group, etc. The photosensitive body having the excellent electrophotographic sensitivity, more particularly the extremely high electrophotographic sensitive at the time of the positive electrostatic charge is obtd. in this way. n COPYRIGHT: (C)1991,JPO&Japio |
