    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： An image forming apparatus enables a high-quality double-side printing of a transfer medium by one-pass method using a simple structure. A latent image is formed and developed on an image carrier (drum) in a process cartridge. A resultant toner image is transferred by a first transfer unit (roller) onto either an upper surface of the transfer medium or a first intermediate transfer body (roller) in a first transfer area. The toner image on the first intermediate transfer body is transferred onto a back surface of the transfer medium in a fourth transfer area via a second intermediate transfer body (belt) and a third intermediate transfer body (roller). The fourth transfer area is located downstream of the first transfer area along a transport path of the transfer medium.

    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.

    摘要： A fixing device includes a fixing nip and a guide member to guide a recording medium transported through a recording media transport pathway to the fixing nip, disposed upstream from the fixing nip in a direction in which the recording medium is transported and facing an unfixed-image side of the recording media. The guide member includes a guide face, the guide face including a first guide face and a second guide face located where at least a trailing-edge of the recording medium approaches the guide member as the recording medium is transported through the recording media transport pathway and which is inclined with respect to the first guide face away from the recording media transport pathway, and a first spur rotatably provided on the guide member and projecting into the recording media transport pathway from a connection portion between the first guide face and the second guide face.

    摘要： An image forming apparatus, forming a color image by successively superposing color images, formed on image carriers of corresponding image forming parts arranged along a rotational direction of an endless moving member, onto the endless moving member or a recording medium conveyed thereby, includes a first part causing a color registration pattern to be created on the endless moving member or the recording medium; a second part obtaining a color registration pattern signal by detecting the color registration pattern; a third part changing image formation timing in the image forming parts based on the color registration pattern signal; and a fourth part causing the endless moving member to rotate in forward and reverse directions after the creation of the color registration pattern. The second part obtains the color registration pattern signal by detecting the color registration pattern during each of the forward and reverse rotations of the endless moving member.
