Abstract
Provided is an electrophotographic photosensitive member capable of suppressing a voltage fluctuation and occurrence of a black spot under a high-temperature/high-humidity environment. The electrophotographic photosensitive member includes: a support; a first intermediate layer formed on the support; a second intermediate layer formed on the first intermediate layer; and a photosensitive layer formed on the second intermediate layer, in which the first intermediate layer contains metal oxide particles having a number-average primary particle diameter of from 30 to 450 nm; and the second intermediate layer contains a cured product of a composition containing an electron transport substance having a polymerizable functional group represented by the formula (1) or (2), and having a molecular weight of from 100 to 1,000, and a crosslinking agent having 3 to 6 groups reactive with the polymerizable functional group represented by the formula (1) or (2), and having a molecular weight of from 200 to 1,300.
