摘要:本发明提供一种图像形成装置,包括形成静电像的像承载体、承载输送显影剂的第一显影剂承载体、配置在比第一显影剂承载体更靠近像承载体移动方向下游一侧的第二显影剂承载体,用在这些显影剂承载体上所承载的显影剂对像承载体上的同一静电像进行显影。具有在通常形成图像时以外之时,使第一显影剂承载体和第二显影剂承载体上所承载的显影剂转移到像承载体上的显影剂消耗模式;在该显影剂消耗模式时进行控制,使得从第二显影剂承载体向像承载体消耗的显影剂消耗量,比从第一显影剂承载体向像承载体消耗的显影剂消耗量多。

主权项:1.一种图像形成装置,包括:形成静电像的像承载体;显影装置,具有承载输送显影剂的第一显影剂承载体、以及配置在比该第一显影剂承载体更靠近像承载体移动方向下游一侧的第二显影剂承载体,并用在这些显影剂承载体上所承载的显影剂,对上述像承载体上的同一静电像进行显影;以及控制装置,在通常形成图像时以外之时,执行使上述第一显影剂承载体和上述第二显影剂承载体上所承载的显影剂转移到上述像承载体上的显影剂消耗模式,其中,上述控制装置,在上述显影剂消耗模式时进行控制,使得从上述第二显影剂承载体向上述像承载体消耗的显影剂消耗量,比从上述第一显影剂承载体向上述像承载体消耗的显影剂消耗量多。
