  • Patent number: 7593662
    Abstract: An image-forming device includes a casing, a driving roller, a conveying belt, a photosensitive unit, a fixing unit, a reading unit, a fan, and a first partition wall. The casing has a wall formed with an air inlet port and defines an inner space. The air inlet port has a top end portion and a bottom end portion. The photosensitive unit is configured to form a predetermined pattern on the conveying belt. The fixing unit has a top edge portion and a bottom edge portion. The reading unit is provided adjacent to the driving roller and is configured to read a predetermined pattern formed on the conveying belt. The fan is provided on an upper section of the inner space. The fan transfers air from inside the casing to outside the casing. The first partition wall is located in the upper section of the inner space. The fan is provided on one side of the first partition wall and the fixing unit is provided on another side thereof. The first partition wall has a bottom end.

  • Publication number: 20090142111
    Abstract: The image-forming device includes an image-forming unit, a fixing unit, a pair of first guides, and a pair of second guides. The recording sheet defines a width in a direction perpendicular to a sheet conveying direction. The image-forming unit forms a developing agent image on the recording sheet. The fixing unit includes a heating and a pressure roller. The heating roller heats the recording sheet discharged from the image-forming unit. The pressure roller presses the recording sheet against the heating roller. The heating roller and the pressure roller provide a nip point where the recording sheet is nipped therebetween. The nip point is offset in a thickness direction of the recording sheet from a plane along which the recording sheet is discharged from the image-forming unit. A sheet conveying path is provided from the image-forming unit to the fixing unit.

  • Publication number: 20090016771
    Abstract: An image forming apparatus configured to effectively prevent a failure in an image is provided. The image forming apparatus of the invention includes a housing, a transport belt for transporting a sheet along a sheet transport face, an image forming portion arranged above the sheet transport face, and a fixing unit arranged on a downstream side of the sheet transport face of the transport belt in a sheet transport direction. The fixing unit includes a heating roller and a pressure roller. A deposit portion where a toner waste deposits is disposed between the image forming portion and the heating roller. The deposit portion is provided with a contact portion that is configured to make contact with an image formation outside region at a trailing edge of the sheet jumping in a direction approaching the heating roller by being separated from the sheet transport face.
