    • Three mounting portions are provided along a direction of rotation of a photoreceptor with an eraser lamp and a corona charger provided on the upstream side of the mounting portions. A first developing unit, an outline unit and a second developing unit, each of which can be attached to and detached from each of the mounting portions, are mounted in this order from the upstream side. When an outline mode is selected, colors of the developing units mounted on the downstream side of the outline unit are displayed on a display portion. When there is no developing unit on the downstream side, no color is displayed, and the copying operation in the outline mode is prohibited. If there is only one developing unit on the downstream side, the copying operation is started by pressing a copying key. If there are a plurality of developing units on the downstream side, a plurality of colors are displayed, and the copying operation is prohibited until one of those colors is designated.
    • 沿着感光体的旋转方向设置有安装部分的上游侧的橡皮灯和设置电晕充电器的三个安装部。 第一显影单元,轮廓单元和第二显影单元可以从上游侧依次安装和拆卸。 当选择轮廓模式时,安装在轮廓单元的下游侧的显影单元的颜色显示在显示部分上。 当下游侧没有显影单元时,不显示颜色,禁止轮廓模式中的复印操作。 如果下游侧只有一个显影单元,则通过按复印键开始复印操作。 如果在下游侧存在多个显影单元,则显示多种颜色,并且禁止复制操作直到指定了其中一种颜色。
