摘要： According to the present invention, a transfer medium is set to be fed. Transfer materials are set to be selectively fed in such a manner that each transfer material has a monochromatic color agent and an identification code assigned thereto, or a plurality of color agents and identification codes assigned thereto. A first feeding means feeds the transfer medium, while a second feeding means feeds the transfer material. A transfer portion transfers a color agent of the transfer material fed by the second feeding means to a transfer medium fed by the first feeding means in accordance with printing data. A detecting means detects the identification code of the transfer material. A controlling means discriminates the type of transfer material in accordance with the identification code detected by the detecting means. The controlling means changes the printing mode in accordance with this discrimination result. Therefore, the feeding operations of the first and second feeding means and the transfer operation of the transfer portion are controlled in accordance with the selected printing mode.
摘要翻译：根据本发明，转印介质被设定为进给。转印材料被设置为以每种转印材料具有单色着色剂和分配给其的识别码或多种着色剂和分配给其的识别代码的方式选择性地进料。第一馈送装置馈送传送介质，而第二馈送装置馈送传送材料。转印部分将由第二进给装置供给的转印材料的着色剂根据打印数据传送到由第一进给装置供给的转印介质。检测装置检测转印材料的识别码。控制装置根据由检测装置检测到的识别码识别转印材料的类型。控制装置根据该判别结果改变打印模式。因此，根据所选择的打印模式来控制第一和第二馈送装置的馈送操作和传送部分的传送操作。

摘要： In a tandem type image forming apparatus of this invention provided with image forming units arranged under an intermediate transfer medium and further, an exposure device arranged under the image forming units, developing devices are arranged so that exposure positions of image carriers and developing rollers come to the opposite sides with toner stirring mixers put between them. Further, there are guides extending under cleaning blades below the cleaning blades to receive falling toners. Further, suction ducts are provided to suck in the air around the developing devices. A slit area formed by the guides and an area of a laser beam projecting unit of the exposure device are arranged while they are shifted. Formed images are exposed at a sufficient exposure light intensity by preventing the laser beam injection unit of the exposure device from being stained and a toner image of high quality is obtained.
摘要翻译：在本发明的串联型图像形成装置中，具有布置在中间转印介质下方的图像形成单元，并且还设置有设置在图像形成单元下方的曝光装置，显影装置被布置成使得图像载体和显影辊的曝光位置到在两侧之间放置调色剂搅拌混合器。此外，还有在清洁刮板下方的清洁刀片下方延伸的导向器以接收落下的调色剂。此外，提供吸入管道以吸引显影装置周围的空气。由导向器形成的狭缝区域和曝光装置的激光束投影单元的区域被布置。通过防止曝光装置的激光束注入单元被染色并获得高质量的调色剂图像，以足够的曝光光强度曝光形成的图像。

摘要： The present invention provides support rollers on both sides of a first tension roller having a small roller diameter and an acute winding angle of an intermediate transfer belt. Ribs installed at both ends of an inner peripheral surface of the intermediate transfer belt are supported by the support rollers to prevent the intermediate transfer belt from bending when a slit formed in a joint of the ribs passes the first tension roller. By doing this, variations in the belt conveying speed of the intermediate transfer belt are reduced and on the intermediate transfer belt of a belt unit aiming at miniaturization, a highly precise transfer image free of image disturbance is obtained.
摘要翻译：本发明提供了具有中等转印带的小辊直径和急弯角的第一张力辊两侧的支撑辊。安装在中间转印带的内周表面的两端的肋由支撑辊支撑，以防止当形成在肋的接头中的狭缝通过第一张力辊时中间转印带弯曲。通过这样做，中间转印带的带输送速度的变化减小，并且在小型化的带单元的中间转印带上，获得了没有图像干扰的高精度转印图像。
