    • An image forming device having a developing unit for visualizing an electrostatic latent image formed on an image carrying body by utilizing a developing agent containing toners and carriers which transfers a toner image to a recording medium to obtain a record image. A patch sensor is provided for detecting the image density of the record image, and it controls toner density stabilization control and an adjustment value and bias voltage in the developing unit according to a value detected by the patch sensor and a value of current flowing in the image carrying body from the developing unit. Thereby, an image forming device is provided which performs stable image density control when a problem is caused during processing of a predetermined number of printing pages, even when a deterioration of the image due to an abnormal property change of a developing agent is caused.
    • 一种图像形成装置,其具有显影单元,用于通过利用含有调色剂的显影剂和将调色剂图像转印到记录介质以获得记录图像的载体,使形成在图像载体上的静电潜像可视化。 提供了用于检测记录图像的图像浓度的贴片传感器,并且根据由贴片传感器检测的值和在该显影单元中流动的电流值来控制显影单元中的调色剂浓度稳定控制和调整值和偏置电压 来自显影单元的图像承载体。 由此,即使当由于显影剂的异常特性变化引起的图像劣化时,也提供了在预定数量的打印页的处理期间引起问题时执行稳定的图像浓度控制的图像形成装置。

    • The present invention provides a development apparatus capable of improving the development pole of a plurality of development rolls and the rotation speed thereof, thus obtaining stable printing quality. A first development roll rotatable in the opposite direction to the moving direction of photosensitive body is disposed in the upstream of it, whereas a group of second development rolls are disposed in the down stream, which development rolls are rotatable in the same direction as the moving direction of photoconductive body and have magnets of the same polarity. The first development roll and the photoconductive body define a peripheral speed ratio ranging from 0.5 to 1.5, while allowing the second development roll and the photoconductive body to define a peripheral speed ratio ranging from 0.6 to 1.5. A development control member is provided between the first development roll and the group of second development rolls. A toner density detector is provided in the downstream of the last one of the group of second development rolls which is disposed in the most significant downstream. A cross mixer and a carrier member are also provided under the first development roll and the group of second development rolls.
