摘要： PROBLEM TO BE SOLVED: To provide a developer cartridge having a high sealing effect. SOLUTION: The developer cartridge includes a side sealing member 150 for sealing the end part of a developing roller and an axial sealing member 156 for sealing all over the whole area of the developing roller in the rotating axis direction. "The upstream end 150d of the side sealing member 150 in the developing roller rotating direction" is positioned in between "the upstream end 190b and the downstream end 190a" of a contact area 190 of the sealing member 156 with the developing roller in the developing roller rotating direction. By having such the constitution, the toner shifting in a direction shown by an arrow P is prevented from reaching the side sealing member 150. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image processing device capable of suppressing a reduction in gradation of an image.SOLUTION: An image processing device comprises: a photoreceptor on which a developer image is formed by a developer being supplied to an electrostatic latent image formed by exposure; and an exposure device for exposing the photoreceptor. The image processing device converts each of multi-gradation pixels constituting a multi-gradation image of image data used by a colored image generation device for transferring the developer image on the photoreceptor with respect to a medium to be transferred that is moved while being brought into contact with the photoreceptor into a two-gradation unit pattern. When converting each of the multi-gradation pixels of a first color into the two-gradation unit pattern, the image processing device converts each of the multi-gradation pixels into a unit pattern constituted of a first line extending in a predetermined direction, upward/downward direction as illustrated in a figure, and a second line extending in a direction intersecting with the first line, rightward/leftward direction as illustrated in a figure, when gradation values of the multi-gradation pixels fall within a predetermined range.

摘要： PROBLEM TO BE SOLVED: To provide a developing cartridge that securely prevents a developer leak from a gap between each end of a developing roller and a housing, and to provide a process cartridge and an image forming apparatus. SOLUTION: A plurality of rib-like projecting parts 74 are formed on each face 72 which faces a roller and on which a side seal 77 is disposed. The projecting parts 74 are formed parallel to one another at predetermined intervals so as to extend obliquely inward widthwise from the downstream side to the upstream side in the direction of the rotation of the developing roller 38, in other words, from a lower position to a higher position. Thus, even if a toner enters a gap between the side seal 77 and the face 72 which faces the roller, the toner entering there can be obstructed by the projecting parts 74. Consequently, it possible to securely prevent a toner leak from a gap between each end of the rubber roller 50 of the developing roller 38 and each face 72 that faces the roller.

摘要翻译：要解决的问题：提供可靠地防止显影剂从显影辊的每个端部与壳体之间的间隙泄漏的显影盒，并且提供处理盒和图像形成装置。解决方案：在面对辊的每个面72上形成有多个肋状突起部分74，并且其上设置有侧密封件77。突出部74以规定的间隔彼此平行地形成，从而从显影辊38的旋转方向的下游侧到上游侧的宽度方向向宽度方向延伸，换句话说，从较低位置到更高的位置。因此，即使调色剂进入侧面密封件77和面向辊子的面72之间的间隙，进入那里的调色剂也可能被突出部分74阻碍。因此，可以可靠地防止调色剂从第二显影辊38的橡胶辊50的每端和面对辊的每个面72。版权所有（C）2007，JPO＆INPIT
