    摘要： A developer device includes two developer rollers arranged opposite to an image carrier. A first developer bias voltage (waveform Z) of a rectangular waveform obtained by superimposing an AC voltage on a DC voltage is applied to one of the developer rollers. A second developer bias voltage (waveform A) obtained by superimposing an AC voltage on a DC voltage is applied to the other developer roller. The waveform A is a waveform obtained by deforming the rectangular wave in the first developer bias voltage such that toner adhered to the image carrier is prevented from being dislodged by toner being subsequently scattered. According to the developer device, an optimal image density can be obtained at a low-density potential.

    摘要： Provided is a deposited-toner measuring apparatus capable of accurate detection of the amount of toner deposited on the toner carrying member, and an image forming apparatus equipped with the aforementioned measuring apparatus and capable of controlling the amount of toner deposited on the toner carrying member to a desired level so as to provide stable image quality at all times. A deposited-toner measuring apparatus that removes a toner layer in a part of the surface of the toner carrying member, detects change in the capacitance at the portion with a toner layer and the portion without such a toner layer, and detects the amount of the deposited toner based on the detection result of the said change in the capacitance.
