CONSTITUTION:A developing tank 51 and a toner hopper 52 are joined with screws or the like to constitute the developing device. An interval collar 53 which keeps the interval between the device and a photosensitive body constant is attached rotatably to the side part of the developing tank 51. A guide member 54 which moves the developing device itself in the horizontal direction is formed on the side face of the developing tank 51 as one body. A positioning part 55 is formed in the front end part of the developing tank 51 correspondingly to a positioning shaft provided on an attaching member of the photosensitive body, and an engaging part 56 which moves the developing device in the horizontal direction is formed in the rear end part as one body. |
