摘要： An image forming apparatus has improved follow-up properties of the fixing rollers between a surface resin layer and an elastic layer beneath it, thereby preventing the generation of a crack and allowing discharge of OHP sheets in a satisfactory manner. A fixing roller and a pressurizing roller are in press contact with each other, and a recording material having an unfixed image is press-conveyed by a pressurizing portion formed by the pair of rollers to effect heat fixing of the image on the recording material. The fixing roller has an elastic layer having a thickness of 1 mm or more and a resin layer having a thickness of 20 &mgr;m to 50 &mgr;m formed on the surface of the elastic layer by firing, and the coefficient of linear expansion of the elastic layer at 150° C. is not larger than 2.7 times the coefficient of linear expansion of the resin layer at 150° C.

摘要： An image forming apparatus, such as a copying machine, has a fixing device for fixing a developer image transferred to a transfer medium, such as paper, with a fixing roller whose surface is coated with a release agent, such as oil, and includes at least one feed passage member for conveying, while contacting, a transfer medium to a transfer region of the apparatus. The feed passage member has a release agent absorbing layer on the surface thereof, and is thus advantageous for preventing release agent from being transferred and adhered to a photo-sensitive drum of the apparatus. The release agent absorbing layer of the feed passage member may contain either porous particles or particles and a binder resin, and be formed on another layer for retaining release agent absorbed by the release agent absorbing layer. The feed passage member preferably constitutes a transfer medium carrying member, which may include a dielectric sheet, for supporting and carrying a transfer medium. The member may alternatively constitute a pick-up roller, a feed guide, and/or a resist roller of the apparatus.
