PURPOSE:To make the temperature variation of a surface photosensitive layer slow and hold it invariably above room temperature, to preventing the temperature of the photosensitive layer from becoming below dew point temperature and prevent the sticking of a water drop and to prevent the blurring and disordering of an image by arranging a heat accumulation material in a photosensitive body. CONSTITUTION:The photosensitive body consists of a photosensitive material vapor-deposited layer 1, a cylindrical Al base plate 2 a heat accumulation part 3, and a shaft 4. The heat accumulation material uses a material such as glycerol, diphenyl oxide, beef tallow, and olive oil with a fusion point which is 10- 50 deg.C higher than the upper limit of the practical use temperature of the copying machine. The heat accumulation material functions so that the layer 1 has slow temperature variation when exposed to abrupt variation in an external temperature (room temperature). When the ambient temperature drops to the most, the accumulation material 3 holds the layer 1 at the temperature higher than the ambient temperature. |
