    摘要： A mechanism for guiding a recording medium into a nip formed between a first rotary member subjected to heating, and a second rotary member pressed against the first rotary member includes a guide member and a biasing member. The guide member is disposed upstream from the nip to guide the recording medium therealong. The biasing member is connected to the guide member to mechanically bias the guide member. The guide member is subjected to a constant biasing force from the biasing member and to a pressure force from the recording medium. The pressure force is opposite the biasing force and variable with a stiffness of the recording medium being guided. The guide member is movable to different operational positions depending on the biasing and pressure forces acting thereon.

    摘要： A fixing device in an image formation apparatus has a heating roller and a backup roller. These rollers are each coated with single silicone rubber layers around the respective peripheries of their core bars. This silicone rubber has a volume resistance value of 1013 &OHgr;·cm or more. The heating roller is charged with electricity of the same polarity as the polarity of toner particles due to frictional electrification caused at the time of feeding of a recording medium. The heating and the backup roller are polarized reverse to the polarity of the recording medium. A quantity of charged electricity on the backup roller is made larger than that on the heating roller. This permits the image formation apparatus to prevent offset from occurring at the time of fixing a toner image onto the recording medium to cope with various types of recording media.
