ORGANIC PHOTORECEPTOR, PROCESS CARTRIDGE, IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an organic photoreceptor which can prevent deterioration in the size or the contrast for forming a latent image by a dot image even when the organic photoreceptor is used for a long time and reduction in the film thickness by wear is continued, and which can produce an electrophotographic image with high gradation and high definition for the formation of an electrophotographic image with resolution as high as≥1,200 dpi, and to provide a process cartridge, an image forming apparatus and an image forming method using the organic photoreceptor. SOLUTION: The organic photoreceptor has a configuration of a charge generating layer and a charge transport layer successively layered on a conductive substrate. In the curve obtained by plotting the integral value of the detected current versus time in the measurement of transient photo-current (TOF) in a 10 V/μm electric field, two tangential lines of the curve make 15°to 45°intersection angle alpha.
