PURPOSE:To improve durability of a photosensitive body by coating a paint which accelerates ozone decomposition to the inside of a cartridge. CONSTITUTION:A corona discharger 3, a developing device 5 and a cleaning device 7 are made integrally attachable and detachable to and from the main unit of a device together with a photosensitive drum 2 as a cartridge K. The cartridge K is made drawable to the outside by opening a door 19' prior to mounting. The casing of the cartridge K is made of a synthetic resin subjected to coloring for light shielding and is of, for example, ''Noryl'' resin, polycarbonate resin, ABS resin, etc. A resin layer dispersed therein with a material which decomposes ozone is provided on the inside of the casing of the cartridge K by, for example, brushing or dip coating method. The material which accelerates ozone decomposition is, for example, paint consisting of dispersing a reducing agent such as manganese oxide (N), lead oxide, platinum powder, ferrosilicon, sodium sulfide or the like into a binder resin. |
