Abstract
An electrophotographic photoreceptor is disclosed which comprises an electroconductive support, a first interlayer formed on the support and containing low-resistance electroconductive particles having a specific resistance of from 10.degree. to 10.sup.4 .OMEGA.cm, a second interlayer formed on the first interlayer and containing high-resistance electroconductive particles having a specific resistance of from 10.sup.4 to 10.sup.8 .OMEGA.cm, and a photosensitive layer formed on the second interlayer. In the electrophotographic photoreceptor, in which the interlayers have an increased thickness for hiding defects present on the support and contain electroconductive particles dispersed therein, the photosensitive layer is free from the electrification performance decrease caused by charge injection thereinto and the interlayers have excellent leak-preventive properties.
