摘要： A fixing device includes a fixing member in contact with an unfixed image constituted of developer T on one side of a recording material P; and a pressure member pressed against the fixing member. The fixing device fixes the unfixed image onto the recording material P by causing the recording material P, charged so as to have a same polarity as a polarity of the developer T, to pass through a gap between the fixing member and the pressure member. In the fixing device, an inflow current into the fixing member Ih is 0 when the recording material P passes through the gap between the fixing member and the pressure member. This securely restrains the developer on the recording material from electrostatically offset to the side of the fixing device, thereby maintaining the formation of high quality images.
摘要翻译：定影装置包括与由记录材料P的一侧上的显影剂T构成的未定影图像接触的固定构件; 以及压靠构件的压力构件。定影装置通过使具有与显影剂T的极性相同的极性的记录材料P通过固定构件和压力构件之间的间隙来将未定影的图像定影到记录材料P上。在定影装置中，当记录材料P通过固定构件和压力构件之间的间隙时，进入固定构件Ih的流入电流为0。这可靠地限制记录材料上的显影剂静电偏移到定影装置的侧面，从而保持形成高质量的图像。
