摘要： A toner density controlling apparatus adapted to control toner density by sensing a T/D level in a developer vessel by using a toner sensor performs a toner density controlling operation on the basis of an output of the toner sensor while maintaining an input control voltage to be applied to the toner sensor at a predetermined level in a definite control range where the toner sensor output decreases proportionally to the T/D level in a linear relation. Conversely, in an indefinite control range where the relationship between the toner sensor output and the T/D level is nonlinear, the input control voltage to be applied to the toner sensor is variably controlled so that the toner sensor output can be adjusted to an upper or lower limit level of the definite control range, and the toner density controlling operation is performed on the basis of the input control voltage. With such an arrangement, even if the definite control range where the toner sensor output decreases proportionally to the T/D level in a linear relation is narrow, the toner density controlling operation can be performed on the basis of the input control voltage in the other control ranges. Therefore, even if an image forming apparatus provided with such a toner density controlling apparatus is used in an extensively varied environment, the toner density can properly be controlled by using a single toner sensor.
摘要翻译：通过使用调色剂传感器感测显影剂容器中的T / D电平来调节调色剂浓度的调色剂浓度控制装置根据调色剂传感器的输出执行调色剂浓度控制操作，同时保持输入控制电压为在调色剂传感器输出以与线性关系的T / D电平成正比的确定控制范围内以预定水平施加到调色剂传感器。相反，在调色剂传感器输出和T / D电平之间的关系是非线性的不确定的控制范围内，施加到调色剂传感器的输入控制电压被可变地控制，使得调色剂传感器输出可以调节到上或下限级别，并且基于输入控制电压进行调色剂浓度控制操作。通过这样的布置，即使调色剂传感器输出与线性关系的T / D电平成正比的确定控制范围较窄，也可以基于另一方的输入控制电压进行调色剂浓度控制控制范围。因此，即使在广泛变化的环境中使用设置有这种调色剂浓度控制装置的图像形成装置，也可以通过使用单个调色剂传感器来适当地控制调色剂浓度。

摘要： In a developing device according to the present invention, a developing roller 8 has a fixed shaft 12 and a sleeve 13. The length of a draw-up magnetic pole N3 provided in the fixed shaft 12 is made shorter than the length of a main magnetic pole N1. Accordingly, the amount of a developer adhering to both ends of an outer peripheral surface of the sleeve 13 is reduced, so that the density of the developer at both the ends of the sleeve 13 is maintained in suitable conditions in a state where the developer is over the main magnetic pole N1.

摘要： A cleaning device according to the present invention has first seals and a second seal adhered so as to partly overlap each other for sealing a space between a housing of the cleaning device and the surface of a photoreceptive member. The first seals include seal bases and a flocked sheet layered on the seal bases. The portion of the seal base where the second seal overlaps is made smaller in thickness than the portion of the seal base where the second seal does not overlap. Therefore, no step is formed in the overlapped portion, thereby preventing toner leakage.
