Provided are an electrophotographic photoconductor that satisfies sufficient wear resistance as well as various characteristics as a photoconductor, and that is little affected by harmful gas or the temperature and humidity environment, and a method for producing such an electrophotographic photoconductor. The electrophotographic photoconductor has at least a photosensitive layer on a conductive substrate. The photosensitive layer contains a diadamantyl diester compound represented by Formula (I) (in Formula (I), R1, R2 and R3 each independently represent a hydrogen atom, a halogen atom, a substituted or unsubstituted C1-C6 alkyl group, a substituted or unsubstituted C1-C6 alkoxyl group, a C6-C20 aryl group or a heterocyclic group; l, m and n each represent an integer from 1 to 4; U and W represent a single bond or a substituted or unsubstituted C1-C6 alkylene group; and V represents an OCO group or a COO group).
