摘要： PROBLEM TO BE SOLVED: To provide a developer cartridge with a structure in which a first opening of a first frame accommodating developer is opened or closed by a second frame that is provided outside the first frame and which can prevent the developer attached to an end portion of the second frame from being scattered to the outside, and a developing unit. SOLUTION: In the outside frame 82 of the toner cartridge 31, a protruding portion 79 is provided in a frame end portion 80 that initially crosses an inside passage hole 89 when the outside frame 82 is moved in a movement direction X from an open position to a closed position. The protruding portion 79 includes a front end 78A and a damming portion 41 that protrudes from the front end 78A to a downstream side in the movement direction X at a position (outside position) that is further away from the inside passage hole 89 than the front end 78A. Even when toner in the inside passage hole 89 is attached to the frame end portion 80 when the outside frame 82 is moved from the open position to the closed position, the toner is dammed up by the damming portion 41 of the protruding portion 79 from the outside.

摘要： PROBLEM TO BE SOLVED: To shorten the time required for collecting residual toner retained on a holding roller into a cleaning unit. SOLUTION: During image formation, residual toner is retained by the holding rollers coming in contact with photoreceptor drums 49 of respective colors. When the apparatus shifts to the operation of recovering the residual toner by a cleaning roller 73, the photoreceptor drums 49 of respective colors and an intermediate transfer belt 69 rotate in the reverse direction to that assigned for the image formation. In addition, developing rollers 56 separate from the photoreceptor drums 49. The hold rollers 57 coming in contact with the photoreceptor drums 49 eject the residual toner to the photoreceptor drums 49, and transfer the toner to the intermediate transfer belt from the photoreceptor drums 49. The intermediate transfer belt 69 is reveresely rotated, thereby a path for conveying the residual toner to the cleaning unit 37 is made short. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：缩短将残留在保持辊上的残留调色剂收集到清洁单元中所需的时间。解决方案：在图像形成期间，残留调色剂由与相应颜色的感光鼓49接触的保持辊保持。当设备转移到通过清洁辊73恢复残留调色剂的操作时，各种颜色的感光体鼓49和中间转印带69沿与指定用于图像形成的反方向旋转。此外，显影辊56与感光鼓49分离。与感光鼓49接触的保持辊57将残留调色剂喷射到感光体鼓49，并将调色剂从感光鼓49转印到中间转印带上。中间转印带69被旋转，从而将残留调色剂输送到清洁单元37的路径变短。版权所有（C）2010，JPO＆INPIT
