ABSTRACT:
The present invention provides a single layer type electrophotographic photoconductor which exhibits the small number of generated black spots in a formed image and exhibits the excellent sensitivity characteristic even when the photoconductor is used for a long time or a photoconductor drum is rotated at a high speed and an image display device which includes the single layer type electrophotographic photoconductor. In the single layer type electrophotographic photoconductor which includes a photoconductive layer containing a binding resin, a hole transporting agent and an charge generating agent, the photoconductor contains a water-repellant polycarbonate resin as the binding resin, and a contact angle of pure water (measured temperature: 25° C.) with respect to the photoconductive layer is set to 100° or more.
