An electrophotographic photosensitive member comprises a drum-shaped or endless-sheet-shaped light-transmissive carrier made of a light-transmissive resin, at least one of the top and bottom surfaces of which has maximum and mean roughness both ranging from 0.3 .mu.m to 4.0 .mu.m, and a photosensitive layer is formed on one of the surfaces of the carrier. The photosensitive layer has a laminate structure composed of a charge generating layer and a charge transporting layer. A light-transmissive layer containing fine particles dispersed in a binder resin may be provided between the light-transmissive carrier and the photosensitive member. An electrophotographic apparatus incorporating this electrophotographic photosensitive member has an image exposure light source such as a laser or an LED array disposed at the side of the photosensitive member adjacent the carrier so as to apply an exposure light to the photosensitive member through the light-transmissive carrier. A facsimile apparatus incorporates this electrophotographic apparatus as a printer.

An electrophotographic apapratus of the type in which a photosensitive member is charged by atmospheric discharge, is equipped with an air filter including a substrate and a catalyst layer formed on the substrate including at least three components of CuO, MnO.sub.2 and a water-soluble polymer. The catalyst layer shows a reactivity with NOx and the water-soluble polymer traps the resultant HNO.sub.3 while retaining a high ozone removing efficiency, whereby the apparatus can show excellent electrophotographic performances even after successive use while preventing deterioration due to ozone, NOx and HNO.sub.3 produced by the atmospheric discharge.

An image-bearing member especially adapted to a very compact electrophotographic apparatus is provided. The image-bearing member has a ratio of the diameter to the length of 1:5 or more, and the surface of the image-bearing member has a relative frictional coefficient against urethane rubber of 0.7 or less with polyethylene terephthalate film as the standard, whereby a cleaning failure and generation of blade scratches on the image-bearing member can be avoided even if it has a small diameter of 45 mm or less. The cleaning effect is ensured if the cleaning blade line pressure is 7 g/cm or higher.
