Abstract

PURPOSE:To determine the relative position with a photoreceptor accurately by forming at least two pieces of projections on both side surfaces of a toner tank, inserting these into the guide grooves formed to the frame of a body case and providing a lever mechanism energizing the projections in a downward direction and in a direction approaching to a photoreceptor. CONSTITUTION:A developing device 16 is unitized, and pins 60 which are projections of two pieces each on one side are provided on both side surfaces of a toner tank 55 by being positioned above and below. These pins 60 are inserted and mounted into the guide grooves 62 formed to the frame 61 of an upper body. The grooves 62 are inclined toward a photoreceptor 12, and a horizontal part 63 exists at the bottom end. An operating lever 66 which turns around a fulcrum shaft 64 and is energized by a tension spring 65 clockwise or counterclockwise in accordance with its position is provided, and at the installing, this lever 66 abuts on the upper pin 60 and is pressing the toner tank 55 downward.
