Image forming apparatus having developing supporters
Abstract:
An image forming apparatus includes a developing device including plural developer supporters provided opposite to a photoconductor, a development bias applying unit for applying a development bias voltage generated by superimposing an AC voltage on a DC voltage to each of the developer supporters, and a phase shifter for shifting a phase of the AC voltage in the development bias voltage in each of the developer supporters.
Abstract(Chinese):

图像形成装置包括：显影装置，包括与光电导体相对设置的多个显影剂支持体;显影偏压施加单元，用于将通过将AC电压叠加到每个显影剂支撑体上的DC电压而产生的显影偏压;以及移相器 用于使每个显影剂支持体中的显影偏压中的交流电压的相位移动。
