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 includes a first opposed body and a second opposed body pressed against the first opposed body. A resilient member exerts a resilient bias to the second opposed body that presses the second opposed body against the first opposed body. A lever assembly is swingable to move the second opposed body against the resilient bias exerted by the resilient member between at least a reduced pressure position where the second opposed body presses against the first opposed body with reduced pressure therebetween and an enhanced pressure position where the second opposed body presses against the first opposed body with enhanced pressure therebetween. A resistance applier engages the lever assembly to exert drag on the lever assembly when the lever assembly moves the second opposed body from the reduced pressure position to the enhanced pressure position.
