摘要： A curl-correcting device includes a first curl-correcting section and a second curl-correcting section. The first curl-correcting section is disposed on a conveying path along which a recording medium is conveyed in a conveying direction. The first curl-correcting section corrects curl in a recording medium having a first thickness. The second curl-correcting section is disposed on the conveying path either upstream or downstream of the first curl-correcting section in the conveying direction. The second curl-correcting section corrects curl in a recording medium having a second thickness greater than the first thickness.

摘要： An image forming device includes a frame, a photosensitive drum, a developing roller, a transfer roller, a heating roller, a backup roller, a peeling claw, and a protection member. The photosensitive drum has a surface on which a latent image is formable. The developing roller develops the latent image to provide a toner image. The transfer roller transfers the toner image onto a recording medium. The heating roller has a heating surface and a shaft supported to the frame and extending in a direction. The backup roller has a shaft supported to the frame and extending in the direction. The backup roller is in pressure contact with the heating roller. The peeling claw has a tip end in sliding contact with the heating surface of the heating roller. The protection member is configured to protect the peeling claw and prevent a user from accessing to the peeling claw.

摘要： In a printer, a scanner unit is formed into a taper shape having a thinner thickness on a side of a pick-up roller in a removing direction of a process unit, to allow the process unit to be removed from the printer. A part of a sheet feeding path is formed in an area between the process unit and a sheet cassette. An image forming position on the sheet feed path is set lower than an upper end of the pick-up roller. Thus, removal of the process unit can be readily performed. Further, the height of the printer at a position of the pick-up roller can be reduced as compared with a case where the scanner unit is not formed into a taper shape.

摘要： A fixing unit is disposed at a position closer to a rear side wall than to a front side wall of a casing. A top wall is formed with a depressed portion depressed toward inside the casing. The depressed portion serves as a sheet discharge tray for receiving a recording medium that has passed through the fixing unit. The sheet discharge tray includes a tray member detachably disposed at the top wall. The rear side wall is formed with an opening through which the fixing unit is removed. When the tray member is disposed at the top wall, the tray member is positioned above and adjacent to the fixing unit and overlaps the fixing unit when viewed through the opening, thereby preventing the fixing unit from being removed from the casing. The fixing unit is removable through the opening when the tray member is detached from the top wall.

摘要： A fixing device is mounted on a main casing of an image forming apparatus. A heating member contacts a recording medium to apply heat thereto while rotating. A heating member includes a roller that rotates about an axis. A frame supports the heating member and includes a frame fixing part that is fixed to the main casing to mount the frame on the main casing. A detecting unit opposes the heating member in an opposing direction to detect a temperature of the heating member and is separated from the heating member. A support member supports the detecting unit. A position of the support member in the opposing direction with respect to the frame is determined at a position closer to the frame fixing unit than the detecting unit. A position of the support member in an axial direction of the roller with respect to the frame is determined at a same position as the detecting unit in the axial direction.

摘要： A fixing unit of an image-forming device having a heating roller, a pressure roller disposed in confrontation with the heating roller, and a case that rotatably supports the heating roller on both longitudinal ends thereof and covers the heating roller from the side opposite the pressure roller, while leaving the pressure roller exposed. A pair of pressure roller support plates, one end of which is supported on the case, rotatably supports both ends of the pressure roller. With this construction, a more compact fixing unit can be achieved than when the case is configured to cover the heating roller and pressure roller entirely. The fixing unit includes a temperature fuse for restraining abnormal temperature rises in the heating roller, and a temperature fuse cover that extends from an inner wall of the case to provide insulation between the temperature fuse and the heating roller. By integrally forming the temperature fuse cover with the case, it is possible to reduce the manufacturing costs of the fixing unit. Support members may also be provided between a bottom surface of the case and the temperature fuse cover to restrain deformation of the temperature fuse cover.
摘要翻译：具有加热辊，与加热辊对置设置的加压辊的图像形成装置的固定单元以及在两个纵向端部可旋转地支撑加热辊的壳体，并且从与压力相反的一侧覆盖加热辊滚筒，同时离开压辊暴露。一对压力支承板，其一端支撑在壳体上，可旋转地支撑加压辊的两端。通过这种结构，可以实现比将壳体完全覆盖加热辊和压力辊时更紧凑的固定单元。定影单元包括用于抑制加热辊中的异常温度升高的温度保险丝，以及从壳体的内壁延伸以在温度保险丝和加热辊之间提供绝缘的温度保险丝盖。通过与壳体一体地形成温度保险丝盖，可以降低定影单元的制造成本。也可以在壳体的底表面和温度保险丝盖之间设置支撑构件，以限制温度保险丝盖的变形。
