摘要： PROBLEM TO BE SOLVED: To provide a developing device, a process cartridge, and an image forming apparatus, suppressing an imbalance in the amount of toner supplied from the toner supply chamber to the developer storage chamber through an outflow opening in the range of the outflow opening. SOLUTION: The toner that is conveyed to the outflow opening 164 while being agitated by the dispense auger 160 flows out from the outflow opening 164 to the developer storage chamber 84. Here, a gradual change portion 166 whose shaft diameter dimension gradually increases in the toner conveyance direction is disposed on a shaft portion 160A of the dispense auger 160 that faces the outflow opening 164. Because the shaft diameter dimension of the shaft portion 160A that faces the outflow opening 164 gradually increases, a pushing force that pushes the toner out through the outflow opening 164 into the developer storage chamber 84 gradually acts on the conveyed toner. In this manner, by causing pushing force to gradually act on the conveyed toner to thereby suppress, in the range of the outflow opening, the imbalance in the amount of the toner supplied to the developer storage chamber 84.

摘要翻译：要解决的问题：为了提供一种显影装置，处理盒和图像形成装置，通过该范围内的流出开口抑制从调色剂供给室供给到显影剂储存室的调色剂量的不平衡的流出口。解决方案：在被分配螺旋推运器160搅拌的同时被输送到流出口164的调色剂从流出开口164流出到显影剂储存室84.这里，轴径尺寸逐渐增大的逐渐变化部分166 在调色剂输送方向上设置在分配螺旋推运器160的面向流出开口164的轴部160A上。由于轴部160A的面向流出开口164的轴径尺寸逐渐增大，因此推动调色剂通过流出开口164进入显影剂储存室84逐渐地作用在所输送的调色剂上。以这种方式，通过使推动力逐渐作用在所输送的调色剂上，从而在流出开口的范围内抑制供应到显影剂储存室84的调色剂量的不平衡。版权所有：（C ）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus and an image forming method with which the appropriate quantity of developer in a developing apparatus can be maintained , and also the deterioration of image quality due to the reduction of the electrification of the developer can be prevented. SOLUTION: Image density information (Pix_per_page) is entered from a ROS to a control part (100), Dif_Pix equivalent to an area coverage obtained by deducting a prescribed value (Base_Pix) from the image density information is computed (102), and the integrated value (Total_Dif_Pix=Total_Dif_Pix+Dif_Pix) of Dif_Pix is computed (104). When the integrated value is negative, the integrated value is replaced with zero (106 and 108), then, compared with a threshold (limit_HAC) (110). When the integrated value is positive, the value left as it is compared with the threshold (106 and 110). When the value becomes equal to or exceeding the threshold, a feed stopping signal is outputted in a tandem type image forming apparatus, on the other hand, in a 4-cycle image forming apparatus, a rotation postponement signal is outputted to the following developing apparatus (112), and an idle rotating cycle is performed and the developer is stirred and supplied (114), thereafter, the feed is restarted or the rotation of the developing unit is restarted, then, the image forming cycle is restarted (118).
