PURPOSE:To make maintenance easy by providing an aperture, which faces a developing device installed in a machine body separately from a unit including a drum, cleaning box, etc., in the unit. CONSTITUTION:In a figure, an upper body 21a of a copying machine 21 divided into two is rotated clockwise with a hinge H as a fulcrum to open a paper feeding path in a lower body 21b to its almost full width. In this state, the correcting work of feed defects of recording paper in the copying machine 21 is made very easy; and further, the structure of the copying machine 21 divided into two is utilized to facilitate attaching and detaching individual functional parts stored in the upper body 21a. That is, a photosensitive drum 25 whose periodically replacement is necessary, a cleaning blade 37 which is worn considerably, etc. are stored as a unit in one case 40, and it is sufficient if this case 40 isd inserted to the upper body 21a for replacement. |
