ABSTRACT:
An electrophotographic receptor includes a conductive support, and a photoconductive layer formed on the conductive support, wherein a minimum electric field strength required for a waveform, which indicates a change in photocurrent generated when a voltage is applied to and a light pulse is radiated on the photoconductive layer with respect to a time, to have a single peak and an upwardly projecting shape is 200 kV/cm or less. The photoconductive layer is constituted by a charge generating layer containing a charge generating substance and a charge transporting layer containing a charge transporting substance. The waveform characteristic of the photoconductive layer can be adjusted by the type and amount of the charge generating substance, the charge transporting substance, or a binder, and a method of manufacturing the charge transporting substance.
