ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC METHOD AND ELECTROPHOTOGRAPHIC APPARATUS

Japanese Patent JP3802787

B2

PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which has high durability, suppresses deterioration of image quality due to rise of residual potential or image blurring and stably gives images of high image quality even when repeatedly used over a prolonged period of time, to provide an electrophotographic method which requires no exchange of a photoreceptor, achieves high speed printing or downsizing of an apparatus due to reduction in the diameter of a photoreceptor and stably gives images of high image quality even in repetitive use by using the above photoreceptor and to provide an electrophotographic apparatus and a process cartridge for the electrophotographic apparatus. SOLUTION: In the electrophotographic photoreceptor obtained by disposing at least one or more photosensitive layers on an electroconductive substrate, a layer formed on the top surface of the photoreceptor includes at least a filler, a binder resin and an organic compound having 10-700 mgKOH/g acid value.
