  • Patent number: 10845749
    Abstract: An image forming apparatus includes a first image forming unit that forms a first toner layer on a medium on which an image is to be formed, a first fixing unit that fixes the first toner layer onto the medium, a second image forming unit that forms a second toner layer on the first toner layer on the medium by using a toner having a melting point lower than a melting point of a toner that is included in the first toner layer, and a second fixing unit that performs, in a state in which a foil layer is superposed on the second toner layer, a fixing operation at a temperature lower than a temperature at which the first fixing unit performs a fixing operation.

  • Patent number: 10095162
    Abstract: A cleaner includes first and second cleaning plates. The first cleaning plate includes a first free end and performs cleaning by causing the first free end to be in contact with an outer circumferential surface of a cylindrical second transfer rotating body including an elastic layer, so that the outer circumferential surface is elastically deformed. The second cleaning plate includes a second free end and performs cleaning by causing the second free end to be in contact with a portion of the outer circumferential surface downstream of, in a rotational direction of the second transfer rotating body, a position where the first free end is in contact with the outer circumferential surface and where the outer circumferential surface is elastically deformed due to the contact of the outer circumferential surface with the first free end so as to have a smallest surface curvature in the outer circumferential surface.

  • Patent number: 9904246
    Abstract: A blowing tube is provided and includes: a passage portion and plural restriction portions. The passage portion includes an inlet passage portion including a first passage space, a first bent passage portion including a second passage space, and a second bent passage portion including a third passage space. One of the restriction portions includes a plate-shaped blocking portion and an air passage portion disposed between one end of the blocking portion and an inner wall surface on an inner side of the second passage space of the first bent passage portion in the bent direction of the second bent passage portion. A bar-shaped member is provided in the third passage space and present in an isolated manner along a longitudinal direction of an opening of the air passage portion of the restriction portion. The air flowing out through the air passage portion collides against the bar-shaped member and diverges.

  • Patent number: 9766570
    Abstract: A blower duct includes a path section and multiple suppressing sections. The path section connects an inlet and an outlet and allows air to flow therethrough. The suppressing sections are provided at different locations in the air flowing direction and suppress the flow of the air. The path section at least has an entrance path section and a first bent path section. One of the suppressing sections is a first suppressing section including a blocking portion and openings. The blocking portion is disposed in the first bent path section and blocks the flow of the air. The openings are disposed at different positions in one direction and include a first opening disposed closest to the inlet at a first height position where a height from a reference base surface of the first bent path section is larger than the remaining opening or openings.
