PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor capable of preventing generation of optical sensitivity degradation, increase of residual potential and degradation of potential change after repetitive use caused by radiation of high energy electron ray to the electrophotographic photoreceptor.SOLUTION: The manufacturing method of electrophotographic photoreceptor is carried out to form a protective layer by curing a hole transport compounds by irradiating a coating film of coating liquid for protective layer which contains curable hole transport compounds with an electron ray. With respect to the dose of electron ray irradiation, defining the numerical value of the dose at a position equivalent to the protective layer as (A); and defining the numerical value of the dose at a position equivalent to a charge generation layer as (B), when the ratio ((A)/(B)) is 2.5 or less, the protective layer is formed after leaving for certain period of time after forming the transport layer.SELECTED DRAWING: None |
