摘要： A bet unit provides an intermediate transfer belt where primary transfer is performed at a part stretching between a drive roller and a tension roller, and a cleaner roller separated from and brought into contact with a part of the intermediate transfer belt stretching between an opposed roller and the drive roller in the downstream side of the opposed roller. The belt unit is detachably attachable to the body with the opposed roller on the operator's side. The tangential line of the opposed roller is substantially vertical at a secondary transfer position. The cleaner roller is disposed in a range enclosed by the intermediate transfer belt, the tangential line of the drive roller parallel to the common tangential line of the peripheries of the tension roller and the opposed roller, and the vertical tangential line of the secondary transfer side of the opposed roller.

摘要： The present invention relates to a toner bottle having a body with a convexly-shaped spiral rib continuously formed on the inside surface thereof and a tip with an opening for toner to flow therefrom. A section for joining the body and the tip includes a first circular face having a slope convex portion that slopes toward the inside, and a second circular face having a toner pump-up portion, the diameter of which is approximately same as that of the body. There is a shutter rotatably disposed on the tip to normally close the opening. The shutter has an opening that fits over the tip opening when the toner bottle is rotated inside the shutter. The shutter may be made of elastic material, and has arcs of different thicknesses. A thicker one of the arcs is used to keep the tip opening closed except when being used in a toner supplying apparatus. The toner bottle allows the toner to flow in a continuous manner, and prevents users from dirtying their hands when replacing toner bottles.
摘要翻译：本发明涉及一种调色剂瓶，其具有连续形成在其内表面上的凸形螺旋肋的主体和具有用于从其流出的调色剂的开口的末端。用于接合主体和尖端的部分包括具有朝向内侧倾斜的倾斜凸部的第一圆形面和具有调色剂泵送部的第二圆形面，其直径与本体的直径大致相同。存在可旋转地设置在尖端上以正常关闭开口的快门。当调色剂瓶在快门内旋转时，快门具有适合于尖端开口的开口。快门可以由弹性材料制成，并且具有不同厚度的弧。除了在调色剂供应装置中使用之外，较厚的一个弧用于保持顶端开口闭合。调色剂瓶允许调色剂以连续方式流动，并且在更换墨粉瓶时可防止使用者弄脏手指。

摘要： The present invention provides a recording apparatus capable of detecting whether a transfer unit is an unused unit or not, including a cover that covers a transfer medium over which a plurality of color images is superimposed to form a color image and has an opening that exposes part of the transfer medium, pasting one end of a seal for detecting whether the transfer unit is an unused unit or not near the opening of the cover in the direction in which the transfer medium moves, pasting the other end of the unused unit detecting seal to the transfer medium through the opening. This allows one end of the unused unit detecting seal to be pasted to the transfer medium through the opening and the other end of the seal to be pasted to the cover near the opening in the direction in which the transfer medium moves. With the unused unit detecting seal pasted in this way, it is possible to detect whether this transfer unit is an unused unit or not.
摘要翻译：本发明提供一种能够检测转印单元是否为未使用单元的记录装置，包括覆盖多个彩色图像叠加以形成彩色图像的转印介质的盖，并且具有露出部分的开口的转印介质的一端粘贴用于检测转印单元是否是未被使用的单元在接近转印方向移动的盖的开口附近，将未使用的单元检测密封件的另一端粘贴到转印介质通过开口。这使得未使用的单元检测密封件的一端通过密封件的开口和另一端粘贴到转印介质上，以沿传送介质移动方向的开口附近粘贴到盖上。以这种方式使用未使用的单元检测密封件，可以检测该转印单元是否是未使用的单元。

摘要： A developing apparatus of the type including a developing roller disposed in a development box, a stirring roller parallel spaced apart from the developing roller, and a toner replenisher pipe disposed in the stirring roller, wherein the stirring roller has a substantially hollow cylindrical shape and includes a plurality of axial ribs extending parallel to a longitudinal axis of the stirring roller and disposed equidistantly from the longitudinal axis, and a plurality of helical blades integral with the axial ribs and skewed relative to the longitudinal axis of the stirring roller, said hollow cylindrical stirring roller being composed of at least two identical segments which are divided by a plane extending through said longitudinal axis of said stirring roller. The stirring roller is simple in construction and can be manufactured at a low cost. The developing apparatus further includes a separator for receiving an excess developer which is removed from the outside surface of the developing roller and direct it unto the stirring roller.
