PURPOSE:To avoid the dropping of toner and at the same time to open large upper and lower frames, by changing a housing from its slanting position to an approximately horizontal position when the housing is drawn out after opening the upper frame. CONSTITUTION:A kit housing 15 containing a photosensitive drum 3, a charger 4, a developer 5 and a cleaner 9 has hooking part 15a and 15b hooked onto guide rail members 20 and 19 of an upper frame 17 and can slide forward freely to the frame 17 and along the members 19 and 20. When a lock catch 21 is released, the frame 17 is separated from a lower frame 18 and moves upward to be kept open large. When the housing 15 is drawn out, a cross arm plate 23 hooked to a pin 2 is moved down to set the housing 15 horizontally. Then the housing 15 is horizontally drawn out. |
