PURPOSE:To improve solvent solubility of a pigment, to enhance electrostatic characteristics, such as photosensitivity and charge retentivity, and to improve red reproducibility by incorporating a specified perylene pigment in a photosensitive layer. CONSTITUTION:The photosensitive layer contains N,N'-bis(di-tert-butyl phenyl)-3,4,9,10-perylenedicarbox-yimi-de. The use of such a perylene pigment as the photoconductor of the photosensitive body or the use of it for the charge generating layer of a functionally separated photosensitive body by using its charge generating ability permit the obtained photosensitive body to be superior in electrophotographic characteristics, such as charge retentivity, sensitivity, residual potential resistance, and stabilized in characteristics at the time of repeated uses, superior also in red reproducibility, and solvent solubility of the pigment, and accordingly, a uniform good coating film to be easily obtained. |
