摘要： PROBLEM TO BE SOLVED: To provide an image formation device that can make a record medium free from contamination.SOLUTION: An image formation device 10 comprises: an image formation unit 100; a fixation device 240 that heats a sheet of paper while conveying the sheet of paper and fixes a developer image on the sheet of paper; a re-conveyance device 560 that inverts the sheet of paper and conveys the sheet of paper again to the image formation unit 100; and a control circuit 600. When the developer image is caused to be formed without forming a margin in the vicinity of an edge of the sheet of paper, the control circuit 600 causes the image formation unit 100 not to form the developer image on the sheet of paper when the sheet of paper initially passes the image formation unit 100, causes the fixation device 240 to heat the sheet of paper and causes the image formation unit 100 to form the developer image on the sheet of paper after the re-conveyance device 560 is caused to convey the heated sheet of paper to the image formation unit 100.
摘要翻译：要解决的问题：提供可以使记录介质不受污染的图像形成装置。解决方案：图像形成装置10包括：图像形成单元100; 固定装置240，其在传送纸张的同时加热纸张并将显影剂图像固定在纸张上; 重新输送装置560，其使纸张反转并将纸张再次传送到图像形成单元100; 以及控制电路600.当在纸张的边缘附近形成显影剂图像而不形成余量时，控制电路600使图像形成单元100不在片材上形成显影剂图像当纸张最初通过图像形成单元100时，导致定影装置240加热纸张，并使图像形成单元100在再传送装置560之后在纸张上形成显影剂图像导致将加热的纸张传送到图像形成单元100。

摘要： PROBLEM TO BE SOLVED: To obtain a transfer device and an image forming apparatus capable of peeling a conveyed recording medium from a conveying member, which rotates to convey the recording medium.
SOLUTION: Negative toner on an intermediate transfer belt 30 is transferred to a sheet member P by repulsing a supporting roll 34 to which negative voltage is applied. The sheet member P is electrified to a more positive side than the supporting roll 34. Furthermore, discharge is generated between the supporting roll 34 and a destaticizing member 42, and a surface of the destaticizing member 42 is electrified with negative charge. By electrifying the surface of the destaticizing member 42 with the negative charge, potential gradient generated between the destaticizing member 42 and the sheet member P is made nearer to potential gradient generated between the sheet member P and the supporting roll 34. Thus, the sheet member P wound around the supporting roll 34 through the intermediate transfer belt 30 is attracted to the destaticizing member 42 side and peeled from the supporting roll 34.

摘要翻译：要解决的问题：获得能够旋转以传送记录介质的传送部件剥离传送的记录介质的传送装置和图像形成装置。解决方案：中间转印带30上的负调色剂通过排斥施加负电压的支撑辊34而转印到片状部件P上。片材P被带电到比支撑辊34更正的一侧。此外，在支撑辊34和去静电元件42之间产生放电，并且去电绝缘元件42的表面带有负电荷。通过以负电荷使去静电部件42的表面通电，使得在去静电部件42和片状部件P之间产生的电位梯度更靠近片材部件P和支承辊34之间产生的电位梯度。因此，片状部件通过中间转印带30缠绕在支撑辊34上的P被吸附到去静电部件42侧并从支撑辊34剥离。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a belt device and an image forming device, for reducing friction between a guide member and a deviation prevention part, and preventing a belt from being deformed.
SOLUTION: A plurality of grooves 74a are formed over a tapered face 74 of a guide part 72, and the grooves 74a are formed linearly to be substantially in parallel to a bus line of a conical face. Each protrusion 74a adjacent to each groove 74a is formed to have a smooth curved face having no acute edge part at a portion in contact with a rib 70. A contact area between the rib 70 and the tapered face 74 can be reduced because each groove 74a is formed on the tapered face 74, and a frictional force generated in a contact part between the rib 70 and the tapered face 74 is thereby reduced.

摘要： PROBLEM TO BE SOLVED: To reduce a stress applied on a belt whose meandering is regulated. SOLUTION: The diameter of a driven roller 17A is larger than that of a driving roller. A guide member 32 is coaxially provided at one end part of the driven roller 17A. The guide member 32 is formed in the shape of a pulley. A rib 31 is formed at one end part of the conveying belt 16 along the moving direction of the conveying belt 16. The rib 31 of the conveying belt 16 is guided by the guide member 32, then, the meandering of the conveying belt 16 is controlled. Since the guide member 32 is arranged coaxially with the driven roller 17A with the diameter larger than that of the driving roller, the stress applied on the conveying belt 16 is reduced along with the meandering regulation.

摘要： PROBLEM TO BE SOLVED: To prevent degradation in operability and save space in an apparatus by allowing replacement of a toner cartridge and removal of a jammed recording paper from the front and the back of an image forming apparatus. SOLUTION: An intermediate transfer belt 6 is in contact with a photoreceptor drum 2 by being wrapped round a photoreceptor drum 2 by a wrap-in roll 15 and a wrap-out roll 16, and a toner image on the photoreceptor drum 2 is transferred to the intermediate transfer belt 6 by a transfer roll 7. A cleaning brush 24 for a belt cleaning device 20 is disposed oppositely to the wrap-in roll 15 via the intermediate transfer belt 6 between them. A transfer roll 8 transfers the toner image on the intermediate transfer belt 6 onto a recording medium 9 conveyed in the front of the full-color printer 1. In this structure, the intermediate transfer belt 6 is not located above a rotary type developing device 5. This makes it possible to replace the toner cartridge 64 from the top of the full-color printer 1 and remove recording paper 9 from the front of the full-color printer 1 in case of a jam.
