摘要：【課題】高い部品精度や調整精度が要求されることなく、安定した現像濃度が得られる構造を実現する。【解決手段】現像剤整流部35の現像スリーブ側の現像剤整流面35aを次のように形成する。まず、現像スリーブ70の表面とコート量規制部36のコート量規制面36aとが最も近接する位置で現像スリーブ70の表面と接する接平面Aを定義する。この場合に、現像剤整流面35aと接平面Aとの間隔が、現像剤搬送方向下流に向かうほど小さくなり、且つ、接平面Aとの間隔の縮小変化率が下流に向かうほど増加するように、現像剤整流面35aを形成する。これにより、現像剤の本流Fmを押し戻すような副流成分が低減すると共に、コート量規制部36と現像スリーブ70との隙間に向けて現像剤を供給するような副流Fsが形成される。【選択図】図4

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus that does not cause an excessive rise in temperature of an intermediate transfer body cleaning device in a black monochrome mode while totally suppressing noise by decreasing blast volume. SOLUTION: An exhaust fan 17 is provided in a housing of the image forming apparatus 69. When a detection temperature of an environment sensor 10 disposed adjacent to a development device 9M reaches a threshold value (T s ) 1 , (T s ) 2 , and (T s ) 3 , a rotation speed is increased to M 1 , M 2 , and M 3 stepwisely to suppress a rise in temperature in the housing. In a black monochrome mode, the development device 9M is stopped, and a rise in temperature of the environment sensor 10 after the start of image forming is delayed, so that switching of the rotational frequency of the exhaust fan 17 is delayed, and the temperature of a belt cleaning device 14 close to a fixing device 15 increases. For this reason, in the black monochrome mode, the threshold values (T s ) 1 , (T s ) 2 , and (T s ) 3 are set lower than in a full color mode to increase the rotational frequency of the exhaust fan 17 at an early stage.

摘要翻译：要解决的问题：提供一种图像形成装置，其在黑色单色模式中不会导致中间转印体清洁装置的温度过度升高，同时通过降低鼓风体积来全面抑制噪声。解决方案：在图像形成装置69的壳体中设置排气风扇17.当与显影装置9M相邻设置的环境传感器10的检测温度达到阈值时（T SB < ＆lt; SB＆gt; 1＆lt; / SB＆gt;，（T SB＆lt; / SB＆gt;）＆lt; SB＆gt; 2＆lt; / SB＆ >，逐步地将转速提高到M 1 ，M 2 和M 3 ，以抑制壳体中的温度上升。在黑色单色模式中，显影装置9M停止，并且图像形成开始之后的环境传感器10的温度上升被延迟，使得排气风扇17的转速的切换被延迟，并且温度靠近定影装置15的带清洁装置14增加。为此，在黑色单色模式中，阈值（T SB SB） 1 ，（T SB S） SB>和（T s ） 3 设定为低于全色模式，以在早期增加排气扇17的旋转频率。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that a low frequency component in vibration of a fan is transmitted to an image forming section when rigidity of a supporting member is low when the fan is supported by a plurality of members. SOLUTION: The fan unit is supported by a fastening supporting section A and a non-fastening pressurized contact supporting section B through an elastic member in an image forming apparatus provided at least with an exposure unit, an image carrier, a developing unit and a transfer unit so that, in vibration of the fan, the comparatively low frequency component which is highly likely to be recognized as banding is positively made to decay and made harder to be transmitted or resonated to the image forming section. At this time, the rigidity of the supporting section A is relatively higher than the rigidity of the supporting section B. COPYRIGHT: (C)2009,JPO&INPIT
