IPC: G03G15/02
Filed: 1990-05-29
Abstract: PURPOSE:To attain the gradual inflow of current into a photosensitive body (PB) by a simple constitution, to prevent the generation of electric damage in the PB 1 and to prolong the using life of the PB by providing the brush charging device with two kinds or more of long and short contacts. CONSTITUTION:Two kinds or more of long and short contacts 4a, 4b constituted so that only their lengths are different and other size and their materials are equal are prepared and a charging brush is arranged so that all the contacts 4a, 4b can be allowed to successively come into contact with the PB 1. Since the surface of the PB 1 is separated from a charging roller on the upstream side in the moving direction of the PB 1, the long contacts come into contact with the PB 1 and the sort contacts do not come into contact with the PB 1, so that the current flowing into the PB 1 is reduced. In accordance with the approach of the surface of the PB 1 to the roller main body, the short contacts also start to contact with the PB 1, so that the number of contacts contacting with the PB 1 is increased and the inflow current is gradually increased. Consequently, current inflow into the PB 1 can be executed without electrically damaging the PB 1.
