摘要

A developer carrying member is comprised of a substrate and a coat layer which covers the surface of the substrate. The coat layer contains at least a binder resin, conductive spherical particles having a number average particle diameter of from 0.3 mu m to 30 mu m and a true density of 3 g/cm<3> or below, and a nitrogen-containing heterocyclic compound, the particles and the compound being dispersed in the binder resin.
