Abstract
Disclosed is an electrophotographic photoreceptor which gives a very low residual potential and scarcely accumulates the residual potential even by repeated use and which varies very slightly in a charging property and sensitivity and has a very excellent stability. The electrophotographic photoreceptor has a conductive support and a photoconductive layer provided on the conductive support. The photoconductive layer contains a charge-generating material, a charge-transporting material, a binder resin and a fatty acid ester compound represented by the following Formula (1): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each represent hydrogen or a saturated or unsaturated aliphatic hydrocarbon group which may have substituents, and n and m each represent an integer of 1 to 10.
