摘要： An image forming apparatus includes a plurality of image carriers arranged side by side along the outer surface of a conveying portion of a transfer belt. The transfer belt is stretched between a first upstream roller and a second downstream roller. An image forming medium is conveyed on the belt so as to have multiple color images transferred thereto. The transfer belt has a swing lever so as to move the belt between a horizontal full color position and an inclined monochrome position. A stationary support roller which is arranged within the transfer belt and at a position nearer to the second downstream roller maintains a position of the image forming medium constant even when a monochrome image is being transferred. In addition, an electrostatic attraction roller located outside the transfer belt is arranged at a specific angle relative to the first roller to assist in the attraction of the image forming medium to the transfer belt.

摘要： An upper body which can be shifted from and toward a lower body through a link mechanism is formed. A drum unit and a toner unit are arranged on the side of the upper body. The upper body is opened in the parallel with respect to the lower body with a predetermined interval, by the link mechanism including arms. In the state where the upper body is opened, the drum unit and the toner unit can be detached from and attached to the printer device in frontward and backward directions, by sliding a sliding member arranged on the upper body.

摘要： A motor starts its rotation, and a clutch is operated to drive both of a first driving force transmission system for color printing, including drum gears, and a second driving force transmission system for monochrome printing, including a drum gear. The clutch is disengaged to stop the first system when a first sensor detects a mark on one photosensitive drum of the first system at the same time that a second sensor detects a mark on one drum driving gear of the first system. Next, when a third sensor detects a mark on another photosensitive drum of the second system at the same time that a fourth sensor detects a mark on another drum driving gear of the second system, the clutch is reengaged. Consequently, positionings of all the photosensitive body drums (drum gears) for color printing to the photosensitive drum (drum gear) for monochrome printing are performed without causing positional differences by inertia at the time of stop.
摘要翻译：电动机开始旋转，并且操作离合器以驱动包括鼓齿轮的用于彩色打印的第一驱动力传动系统和用于单色打印的第二驱动力传动系统，包括鼓齿轮。当第一传感器检测到第一系统的一个感光鼓上的标记时，第二传感器检测到第一系统的一个鼓驱动齿轮上的标记的同时，离合器被分离以停止第一系统。接下来，当第三传感器在第四传感器检测到第二系统的另一个鼓驱动齿轮上的标记的同时检测到第二系统的另一感光鼓上的标记时，离合器被重新接头。因此，进行单色打印的感光鼓（鼓齿轮）的全部用于彩色印刷的感光体鼓（鼓齿轮）的定位，在停止时不会产生惯性的位置差异。
