    • An image forming apparatus may include controls for changing a state of a developing roller from a stopped state to a rotating state. The change in state may be used to avoid deterioration of toner and/or a surface of the developing roller. Changes in state may occur at various times including at a timing corresponding to an outside of an image formation area, a timing corresponding to an inside of an image formation area and the like. In one arrangement, a first developing roller may continue to rotate (e.g., during monochrome printing), while one or more other developing rollers are switched between a stopped state and a rotating state. Alternatively or additionally, a roller which is caused to change states may remain stopped between the timing corresponding to a rear end of an image formation area and a timing corresponding to a front end of an immediately subsequent image formation area.
    • 图像形成装置可以包括用于将显影辊的状态从停止状态改变为旋转状态的控制。 可以使用状态的改变来避免调色剂和/或显影辊的表面的劣化。 包括在对应于图像形成区域的外部的定时,对应于图像形成区域的内部的定时等的各种时刻可能发生状态变化。 在一种布置中,第一显影辊可以继续旋转(例如,在单色打印期间),而一个或多个其它显影辊在停止状态和旋转状态之间切换。 或者或另外,引起改变状态的辊可以在对应于图像形成区域的后端的定时和对应于紧接着的后续图像形成区域的前端的定时之间保持停止。
