  • Patent number: 10175616
    Abstract: A fixing device includes a heating body, a pressuring body, a charging part and a collecting part. The heating body contacts with a medium having a toner image while rotating to heat the medium. The pressuring body forms a nip with the heating roller while rotating to pressure the medium passing through the nip with the heating body. The charging part is positioned to face to the heating body and electrically discharges to electrically charge the heating body with the same polarity as polarity of toner. The collecting part is positioned to face to a position at an upstream side with respect to a facing position on the heating body to the charging part and at a downstream side with respect to a forming position of the nip in a rotating direction of the heating body, and collects impurities caused by the medium passing the nip by absorbing or removing.

  • Patent number: 9772583
    Abstract: A cleaning device includes a cleaning member, a collecting roller and a cleaning blade. The cleaning member is disposed to be rotatable while being in contact with a surface of an image carrier configured to carry a toner image to the surface. The collecting roller is disposed to be rotatable while being in contact with the cleaning member at a downstream side from the image carrier in a rotation direction of the cleaning member. The cleaning blade is disposed while being in contact with the collecting roller in a counter direction with respect to rotation of the collecting roller at a downstream side from the cleaning member in a rotation direction of the collecting roller. The collecting roller is formed so as to have larger surface roughness at an end than that at a central part in an axial direction.

  • Patent number: 9551959
    Abstract: An image forming apparatus includes a toner containing portion, a first conveying member, an image conveying portion, and an image forming portion. The first conveying member is configured to convey the toner in a conveyance direction within the toner containing portion. The image conveying portion includes a surface layer portion having a first end portion located at an upstream side in the conveyance direction and a second end portion located at a downstream side in the conveyance direction. The first end portion has a larger layer thickness than second end portion. The image conveying portion is configured to convey a toner image formed on a surface of the surface layer portion at a predetermined image forming position, to a transfer position for transfer to a transfer target medium. The image forming portion is configured to form the toner image on the surface layer portion by using the toner being conveyed.
