  • Patent number: 11585377
    Abstract: A holder has a protrusion which protrudes from a side surface at a side opposite in an axial direction with respect to a rolling element held in a pocket toward the side opposite in the axial direction. An oil supply hole which penetrates through the holder from the side surface to a surface at a side of the rolling element in the axial direction is formed in the holder. When the holder rotates, the protrusion guides oil into the oil supply hole, and the oil is introduced from the side surface of the holder to the surface on the side of the rolling element.

  • Patent number: 9377725
    Abstract: A fixing device includes a hollow, open-sided stationary heat roller, a flexible fuser belt, a fuser pad, a rotatable pressure member, a reinforcing member, and a sealing mechanism. The heat roller defines an elongated longitudinal side opening that opens into a hollow interior thereof. The fuser belt is looped for rotation around the heat roller to transfer heat radially outward from the roller circumference. The fuser pad is held substantially stationary along the roller opening outward from the roller interior and inward from the loop of the fuser belt. The pressure member is pressed against the fuser pad through the fuser belt to form a fixing nip. The reinforcing member is disposed within the roller interior to thrust against the fuser pad through the roller opening. The sealing mechanism is disposed on the roller opening to prevent foreign matter from entering the roller interior through the roller opening.
