Abstract

PURPOSE:To prevent developing agents from dispersing in a camera by providing mobile sealing material, which prevent developing agents from dispersing through the gap between a image supporting substance and a developing mean as well as a cleaning mean, and a means for controlling the gap sealing action of said sealing material. CONSTITUTION:Sealing meterials 22, 22 are disposed respectively under the developing device 5 and cleaning device 7, and by springs 23, 23' brought into press-contact slightly with the surface of sensitive substance drum 2, and bridge the gap. By such arrangement, it is possible to provent the developing agents, which drop from a developing roll 5 in the developing device and also are removed by a blade 71 of the cleaning device, from dispersing in a camera through the gap. Hence, when these devices are separeted together with the sensitive substance drum a main device, it is possible to be free from the risk of scattering the developer therearound.
