摘要： An image forming apparatus of the present invention includes a plurality of components that form image forming means and should be mounted or dismounted in a preselected order. Following one of the components with respect to the preselected order cannot be dismounted from the apparatus until preceding one of the same has been dismounted. The components are mounted to the apparatus in the reverse order. The components unremovable from the apparatus and positioned above the removable components in a preselected dismounting direction are retractable.

摘要： An image forming apparatus is provided which can selectively drive a plurality of developing units by a simple structure accommodated in a small space. Two image stations are arranged along a direction of movement of an intermediate transfer belt. Each of the image stations is provided with a plurality of developing units arranged around a photosensitive drum. A developing unit driving system drives the plurality of developing units. A switching mechanism switches a transmission path of a power generated by the developing unit driving system so that the power is selectively transmitted to one of the developing units.

摘要： An image forming apparatus includes an intermediate transfer member, a sensor, and two image forming units. Each of the image forming units includes an image carrier, an image writer, two development rollers, and a switcher. The image writer writes an electrostatic latent image on the image carrier. Each of the development rollers selectively driven by the switcher visualizes the electrostatic latent image to form toner images in four colors. The toner images are transferred and superimposed onto the intermediate transfer member to form a color toner image. The color toner image is transferred onto a transfer sheet. One or more marks are formed on the intermediate transfer member. The sensor detects one of the marks. The image writer starts writing in synchronism with a sync clock signal of the image writer output immediately after the sensor detects the mark or output after a predetermined time period elapses after the sensor detects the mark.
摘要翻译：图像形成装置包括中间转印部件，传感器和两个图像形成单元。每个图像形成单元包括图像载体，图像写入器，两个显影辊和切换器。图像写入器将静电潜像写入图像载体上。由切换器选择性地驱动的每个显影辊可以使静电潜像可视化，以形成四种颜色的调色剂图像。调色剂图像被转印并叠加到中间转印部件上以形成彩色调色剂图像。彩色调色剂图像被转印到转印纸上。在中间转印部件上形成一个或多个标记。传感器检测到其中一个标记。在传感器检测到标记之后经过预定时间段之后，图像写入器开始与传感器检测到标记或输出之后的图像写入器输出的同步时钟信号同步进行写入。

摘要： A two-station type color image forming apparatus of the present invention includes intermediate members configured to support only a developing device or the developing device and image forming means other than an image carrier. The intermediate members are selectively locked to or unlocked from the body of the image forming apparatus. Members constituting the image forming means each can be simply replaced alone in accordance with its life.
