摘要： The purpose of the present invention is to provide a conductive contact material, the contents of which do not generate soil on a charged body not only during initial use but also after repeated use. A conductive contact material consists of thermoset urethane material containing an antioxidant within a range from 0.1 to 0.3% by weight, and an inorganic ion electrically conducting agent with in a range form 0.01 to 2.00% by weight. After ozone exposure or the like, molecule chain scission of the base material and antioxidant leads generation of active monomers and origomers. However, the conductive contact material containing the above specified proportion of an antioxidant and an inorganic ion electrically conducting agent prevents generation of active monomers and origomers which are soiling source for a charged body. The conductive contact material also prevents antioxidant itself from being a soiling source. The employment of conductive contact material on a contact type charging device such as a transfer roller avoids disadvantages such as image noise caused by soil on a charged body without involving a large image forming apparatus and complex manufacturing process.
摘要翻译：本发明的目的是提供一种导电接触材料，其内容物不仅在初始使用时而且在重复使用之后不会在带电体上产生污垢。导电接触材料由含有0.1至0.3重量％范围内的抗氧化剂的热固性聚氨酯材料和0.01至2.00重量％范围内的无机离子导电剂组成。在臭氧暴露等之后，基材和抗氧化剂的分子链断裂导致活性单体和起始物的产生。然而，含有上述指定比例的抗氧化剂和无机离子导电剂的导电接触材料防止产生作为带电体污染源的活性单体和起源物。导电接触材料还防止抗氧化剂本身成为污染源。在诸如转印辊之类的接触式充电装置上使用导电接触材料避免了诸如图像噪声等引起的图像噪声，而不涉及大的图像形成装置和复杂的制造工艺。

摘要： Image density is detected by a B/W ratio detection integrator 30 via a video signal 11 from a video controller 40 when an image signal is inputted. When a latent image formed on a photosensitive body 7 in accordance with the image signal is transferred to a transfer material 12 by a transfer charging device 8, a transfer current of the transfer charging device 8 is controlled in a timely fashion by a CPU 20 in accordance with the image density detected from this image signal, thus ensuring optimum transfer efficiency. Even when the environment and printing pattern change for each part of a single-page image, this makes it possible to deal accurately with these changes to ensure stable transfer efficiency and good imaging.
