A fixing belt is heated by electromagnetic induction. The fixing belt has a heat generating layer that has a thickness not greater than 40 μm and a releasing layer that has a thickness not less than 10 μm. A toner that includes at least a binder resin, a colorant, and a mold releasing agent, and has a glass transition temperature in a range of 35° C. to 50° C. and an outflow-start temperature in a range of 80° C. to 110° C., is used.
摘要:
A fixing device including a fixing belt, a drive roller and a press roller. The drive roller is configured to drive the fixing belt, and press roller is arranged so as to face the drive roller across the fixing belt, and exert pressure toward the fixing belt. The drive roller and the press roller are able to rotate so that the peripheral velocity of the drive roller is greater than the peripheral velocity of the press roller. According to the fixing device image defects, including image difference, are less likely to occur when fixing an image on a recording sheet.

An image-fixing apparatus including a fixing belt; a fixing member; a pressure member; and a heating source, wherein the fixing belt is heated by the heating source, wherein the fixing member is brought into pressure contact with the pressure member via the fixing belt to form a nip and a paper carrying an unfixed toner is allowed to pass through the nip, thereby fixing the unfixed toner on the paper, and wherein the toner to be used includes a binder resin, a colorant, and a releasing agent, and wherein the toner has a ½ flown-out temperature of 115° C. to 145° C. and has a storage elastic modulus (G′) at 190° C. of 200 Pa or more.
摘要:
A transfer-fixing unit for use in an image forming apparatus having an intermediate transfer member and a transfer-fixing unit, which includes a pressure member and a transfer-fixing member. The intermediate transfer member receives a toner image thereon. The transfer-fixing member has a deformable surface layer thereon, and directly receives the toner image from the intermediate transfer member, and transfers and fixes the toner image to a recording medium while deforming the surface layer in response to surface irregularities of the recording medium. The transfer-fixing member forms a nip portion with the pressure member and presses the recording medium at the nip portion when the recording medium passes through the nip portion with a nip time.
摘要:
An intermediary transfer apparatus for transferring an unfixed image from an intermediary transfer member to a recording medium is disclosed. The intermediary transfer apparatus includes a heating unit for selectively heating a prescribed portion of the intermediary transfer member on which the unfixed image is situated, in a width direction of the intermediary transfer member, the width direction of the intermediary transfer member perpendicularly intersecting the direction in which the unfixed image is conveyed.
摘要:
A fixing device including a magnetic field generating device to generate a magnetic field, a fixing member to heat a recording material by heat generated in a first recording material passing area having a first width on the fixing member by electromagnetic induction heat generation by the magnetic field formed by the magnetic field generating device, a pressing member to form a nip portion where the pressing member and the fixing member press against each other to fix an unfixed image on the recording material, and at least one radiation heating device configured to heat a second recording material passing area having a second width.
摘要:
A fixing device for fixing image information on a recording medium passing a nip of the present invention includes a rotatable member for transferring and conveying a non-fixed image, a first heating means for heating an image present on the rotatable member and a rotatable pressing member forming a nip in combination with the rotatable member. A heat pipe extends in parallel to the axis of the rotatable member. A radiating member is positioned at one end of the heat pipe while a heating member is positioned at the other end of the heat pipe.
