PURPOSE:To improve chargeability of an electrophotographic sensitive body, to reduce relative humidity at high temp. and under high humidity, and to prevent dewing of the photosensitive body at low temp. by imparting absorptivity for infrared rays to an electroconductive substrate and/or a photosensitive layer. CONSTITUTION:A compd. having absorptivity for infrared rays is incorporated into an electroconductive substrate 11 and/or a photosensitive layer 15 of a photosensitive layer. Suitable electroconductive substrate 11 having absorptivity for infrared rays is a metal such as Al coated with CuO, etc. by vapor deposition or sputtering, etc. Suitable absorbent for infrared rays to be incorporated into a photosensitive layer 15 is CuO, etc. Thus, chargeability of an org. photosensitive body is improved, relative humidity of atmosphere of a photosensitive body is reduced even at high temp. and under high humidity, and dewing of the photosensitive body at low temp. is prevented. |
