    • A developing apparatus, an image formation apparatus and a process cartridge is provided. Even though the sealing materials of the initial developer container are stripped off in such a way that the process cartridge having the developing apparatus is tilted, the initial developer can be uniformly supplied along the central axis line of the developer carrier. The developing apparatus performs a self toner control and has an initial developer case 10 for containing the non-used initial developer 3c that is input into the developer containing space S. The initial developer case 10 is divided internally into a plurality of partition spaces 10b along the direction of the central axial line D of the developing sleeve 4, so that a plurality of partitions 10c is formed inside the initial developer case 10. Based on the opening 10a for inputting the initial developer, the partition surface F facing to the partition space 10b of each partition 10c is tilted from an imaginary plane G perpendicular to the central axial line D of the developing sleeve 4 toward one end H along the direction of the central axial line D of the developing sleeve 4.
    • 提供了显影装置,图像形成装置和处理盒。 即使初始显影剂容器的密封材料被剥离,使得具有显影装置的处理盒倾斜,初始显影剂可以沿显影剂载体的中心轴线均匀地供应。 显影装置执行自调色剂控制,并且具有用于容纳输入到显影剂容纳空间S中的未使用的初始显影剂3c的初始显影剂盒10.初始显影剂盒10被内部划分成多个分隔空间10b 显影套筒4的中心轴线D的方向,使得在初始显影剂盒10内部形成有多个隔板10c。基于用于输入初始显影剂的开口10a,面向分隔空间的分隔面F 每个分隔件10c的10b从垂直于显影套筒4的中心轴线D的假想平面G沿着显影套筒4的中心轴线D的方向向着一端H倾斜。

    • A printer having one roller of a transportation roller pair attached to cover renders the mechanism pressing the transportation roller pair together and the damping mechanism used when opening the cover using few parts, compactly, and at low cost. A damper spring 27 prevents the cover unit 3 of the printer 1 from opening suddenly and forcefully. A roller support lever 38 having the first follower roller 33b disposed to the distal end thereof is attached rotatably and movably to the cover unit 3. The roller support lever 38 is urged by the damper spring 27, and the first follower roller 33b on the distal end thereof is pressed to the first transportation roller 33a on the printer frame 11 side. The damper spring 27 functions as the damping mechanism when the cover unit 3 opens, and as the pressure mechanism of the first transportation roller pair 33 when the cover unit 3 is closed.
    • 具有连接到盖的输送辊对的一个辊的打印机使得将输送辊对压在一起的机构和当使用少量零件打开盖时所使用的阻尼机构紧凑且低成本。 减震器弹簧27防止打印机1的盖单元3突然且强力地打开。 具有设置在其远端的第一从动辊33b的辊支撑杆38可旋转地并可移动地附接到盖单元3.辊支撑杆38被阻尼弹簧27推动,并且第一从动辊33b在远端 其端部被按压到打印机框架11侧上的第一输送辊33a。 当盖单元3打开时,减震弹簧27用作阻尼机构,并且当盖单元3关闭时用作第一输送辊对33的压力机构。
