摘要： A bias voltage-applying unit applies a bias voltage to an insulating toner that includes an electric charge, by making a contact with the insulating toner. A light irradiating unit irradiates the insulating toner with a light. An electric-charge control unit controls an electric charge amount of the insulating toner by causing an optical switch phenomenon in which an electrostatic charge amount of the insulating toner changes, by irradiating the insulating toner with the light using the light irradiating unit while applying the bias voltage to the insulating toner using the bias voltage-applying unit.

摘要： A development apparatus can uniform a toner density by controlling the phase of a toner density fluctuation, and can inhibit fluctuation of the toner density and variation of the toner charge amount. The development apparatus is configured to have a phase control mechanism, which forms a dividing point at a predetermined point (e.g., an opening section provided on a partition plate between two screws) in a flow of a developer within the development apparatus in which a toner density fluctuates spatially due to toner replenishment or toner consumption caused by development, causes the developer divided at the dividing point to pass through different paths (path 1, path 2), thereby shifts a phase of the fluctuation of the toner density within the developer, and thereafter causes thus obtained developers having shifted phases to merge with each other, to perform phase control. The developers spatially having toner density fluctuations are superimposed with shifted phases, thereby a high toner density and a low toner density are averaged so that the toner density is uniformed.
摘要翻译：显影装置可以通过控制调色剂浓度波动的相位来均匀调色剂浓度，并且可以抑制调色剂浓度的波动和调色剂带电量的变化。显影装置被配置为具有相位控制机构，该相位控制机构在显影装置内的显影剂流中在预定点（例如，设置在两个螺钉之间的隔板上的开口部分）上形成分割点，其中调色剂由于调色剂补充或由显影引起的调色剂消耗，密度在空间上波动，导致在分割点处划分的显影剂通过不同的路径（路径1，路径2），从而使显影剂内的调色剂浓度的波动相移，然后使因此获得的相位相位变得相互合并的显影剂进行相位控制。在空间上具有调色剂浓度波动的显影剂与偏移相叠加，从而平均调色剂浓度高和调色剂浓度低，使得调色剂浓度均匀。

摘要： An applied voltage control device includes a potential difference determiner and an applied voltage controller. The potential difference determiner determines a potential difference between a maximum alternating current development voltage and a minimum alternating current development voltage, depending on a developing potential that is an absolute value of a difference between an average electric potential of an alternating current development and an electric potential of a latent image, so as to maintain a constant maximum voltage of a developing bias in the alternating current development. The applied voltage controller controls an alternating current development voltage, applied to move developer from a developer bearer to the latent image, so as to obtain the potential difference determined by the potential difference determiner.
