PURPOSE:To obtain the electrophotographic device which prevents interference fringes from being formed in an image and is free from an image defect by limiting the extent of the surface roughness of the conductive base body of a photosensitive body. CONSTITUTION:The waveform of exposure for latent image formation is about 780nm and the conductive base of the photosensitive body has a surface satisfying respective conditions of 0.4-2.0mum maximum height (Rmax), 0.1-0.6mum surface waviness (Wc), 5-30mum mean peak intervals, 0.1-0.5mum mean center line roughness (R3), and 0.3-1.9mum 10-point mean roughness (Re). For example, even when a semiconductor laser is used as an exposure light source for latent image formation on the photosensitive body and the photosensitive body is irradiated with light with about 780nm wavelength, no interference fringes due to reflected light on the base surface are formed in the image on a sensitive body device for electrophotography. |
