Abstract
Provided is a photoconductor for electrophotography having high sensitivity, low residual potential, and good wear resistance and contamination resistance, and that is less likely to cause light-induced fatigue and filming, and also exhibits good potential stability before and after repeated printing, even without a surface protective layer formed on a photosensitive layer. Provided also are a process of producing the photoconductor and an electrophotographic apparatus. The photoconductor for electrophotography may be a single-layer-type photoconductor or a multi-layer-type photoconductor and includes a conductive substrate and a photosensitive layer formed on the conductive substrate and including a hole transport material having a structure represented by general formula (1) below; a binder resin having a repeating structure represented by general formula (2) below; and at least one electron transport material having a structure represented by general formulae (ET1) to (ET3) below:
