PURPOSE:To change position safely, by providing a latch member latchable to an operation handle only when a developer case main body is at a development position, and the operation handle to change the position of the developer case main body. CONSTITUTION:A developer is provided with a support stand operating handle 42, and when the handle 42 is turned downward toward the arrow in Figure, a shaking stay 39 moves right in Figure via an L type lever 41, each shaking lever 37 rotates clockwise by taking a pin 55 as a center from vertical to a tilted position. As a result, a support stand 5 is shaked clockwise and a development roller 25 detaches from a photosensitive drum 3 with this shaking. The handle 42 is locked with a latch member 46 at a normal development position. Thus, the position of the development case main body can be changed easily and safely only with the operation to the operating handle. |
