摘要： A heat fixing apparatus for fixing an unfixed image formed on a recording material is provided with a discharge roller coming into contact with a recording material and positioned at a downstream side of a fixing nip in a conveying direction of the recording material, and, for improving a fixed image tailing phenomenon, applies a bias voltage to at least either of a fixing film and the discharge roller. In case the recording materials are fed in continuous manner, a bias voltage while the recording material is passed through the fixing nip is elevated or lowered according to a number of heating of the recording materials. In this manner it is possible to reduce deposition of toner, paper powder, dust etc. to the surface of the fixing member, generated particularly in case of a continuous supply of the recording materials under a high bias voltage, thereby preventing generation of an image defect such as blobs resulting from a toner contamination.
摘要翻译：用于固定形成在记录材料上的未定影图像的热定影装置设置有与记录材料接触并定位在记录材料的传送方向上的定影辊隙的下游侧的排出辊，并且为了改善固定图像拖尾现象，将偏置电压施加到定影膜和排出辊中的至少一个。在记录材料以连续方式进给的情况下，记录材料通过定影辊隙的偏置电压根据记录材料的加热次数而升高或降低。以这种方式，可以减少调色剂，纸粉，灰尘等沉积到定影部件的表面，特别是在高偏压下连续供应记录材料的情况下产生，从而防止产生图像缺陷，例如由调色剂污染导致的斑点。

摘要： An image forming apparatus is provided with an image heating apparatus for holding and conveying a recording material bearing an image in a nip between a heating member and a pressurizing member to heat the image on the recording material. The image forming apparatus has a bias applying portion for applying a bias to at least one of the heating member and the pressurizing member and a bias setting portion for setting an amount of the applied bias. In the case that a recording material(s) having a first width is fed and thereafter a recording material is to be fed, the bias setting portion sets the amount of the applied bias based on the number of the recording material(s) having the first width that have been fed and the time from the feeding of the recording material(s) having the first width to the feeding of the recording material having the second width.
