Description

technical field

[0001] The present invention relates to a novel quinone compound, and more specifically, to a novel quinone compound useful as a charge-transporting material such as an electrophotographic photoreceptor (hereinafter simply referred to as a "photoreceptor"). Furthermore, the present invention relates to a photoreceptor for electrophotography and an electrophotographic device, in particular, to a photoreceptor for electrophotography used in an electrophotographic printer, copier, etc., in which a photosensitive layer containing an organic material is provided on a conductive substrate. body and an electrophotographic device using the photoreceptor. Background technique

[0002] Conventionally, as a photosensitive layer of a photoreceptor for electrophotography, an inorganic photoconductive substance such as selenium or a selenium alloy, and an inorganic photoconductive substance such as zinc oxide or cadmium sulfide dispersed in a resin binder have been used. ...
