    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 fusing apparatus for fusing a toner image onto a recording medium using heat and pressure includes a fusing roller; an endless pressing belt disposed opposite the fusing roller; and a pressing member for pressing the endless pressing belt onto the fusing roller. A recording medium with a transferred toner image is passed through a fusing nip between the fusing roller and the pressing belt. The fusing roller includes positive and negative crown portions along the axial direction. The pressing member includes convex and concave surface portions along the longitudinal direction. When the pressing member is pressed onto the fusing roller, the positive and negative crown portions of the fusing roller are engaged with the concave and convex surface portions, respectively, of the pressing member. The pressing member exerts a greater pressing force on the fusing roller at a central portion than at an end portion.

    摘要: A fixing unit where an operating force for releasing a nip can be reduced with a small-sized configuration. The fixing unit has a heating roller including a heating element, a pressure belt, pressure arms, pressure springs, and nip load releasing units. The pressure belt is supported in an intermediate position between the pressure arms 3. One end portions of the pressure arms are brought into contact with the pressure springs respectively. The other end portions of the pressure arms are brought into contact with the nip load releasing units respectively. When a load applied to the pressure belt is released by the nip load releasing units, the other end portions of the pressure arms move away from the heating roller.
