Abstract
The present invention provides an electrophotographic photoconductor including an intermediate layer having sufficient electron transportability and blocking property and capable of suppressing image defects such as fogging and dots. The electrophotographic photoconductor according to the present invention includes a conductive support, a photosensitive layer disposed on the conductive support, and an intermediate layer disposed between the conductive support and the photosensitive layer, wherein the intermediate layer comprises metal oxide particles and a binder resin. The metal oxide particles are surface-treated with an alkoxysilane oligomer represented by the following Formula (1):SiO(OR)(OR)  Formula (1) wherein Rand Reach individually represents a Calkyl group; n represents an integer of 2 to 20; and m and l each individually represents an integer of 0 or more and satisfies an equation of m+1=2n+2.
