PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which prevents image defects due to lowering of sensitivity liable to occur in high-speed copying and in a low temperature and low humidity environment when an electrophotographic image is formed, that is, lowering of image density due to potential variation of a solid black image portion and lowering of sharpness due to thinning of letters in reversal development, and by which a high density and high resolution clear electrophotographic image is stably obtained, and to provide a process cartridge using the electrophotographic photoreceptor, an image forming method and an image forming apparatus. SOLUTION: The electrophotographic photoreceptor has a surface layer containing a mixed compound having a chemical structure of the formula: X-(CTM group)<SB>n</SB>-Y, wherein when a composition ratio of a compound as the greatest component of the mixed compound having an n-based distribution is represented by x and that of a compound as the second-greatest component by y, x+y is≤99%, and an antioxidant.
