    摘要： An electrophotographic photosensitive member has an electroconductive substrate and a photosensitive layer formed thereon. The photosensitive layer contains an acetal resin having a component unit represented by the following formula (1): ##STR1## wherein X is ##STR2## R.sub.1 is a substituted or unsubstituted aryl group and a substituted or unsubstituted heterocyclic group; R.sub.2 is a hydrogen atom and a substituted or unsubstituted alkyl group; R.sub.3 is a substituted or unsubstituted alkyl group; A is a substituted or unsubstituted heterocyclic group and ##STR3## R.sub.4 is a substituted or unsubstituted heterocyclic group; R.sub.5 is a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group and a substituted or unsubstituted heterocyclic group; and n and m are each 0, 1, 2 and 3.

    摘要： An electrophotographic photosensitive member, having a support, and an intermediate layer and a photosensitive layer disposed on the support in this order; the intermediate layer having a coated powder comprising a coating layer and barium sulfate fine particles coated with the coating layer; and the coating layer comprising tin oxide. The above intermediate layer is usable for constituting an electrophotographic apparatus providing stable potential properties and good image quality under overall environmental conditions including low-temperature and low-humidity condition to high-temperature and high-humidity condition.
