Abstract: A fixing device includes a fixing unit configured to heat a sheet to fix an image on the sheet, a heating unit configured to heat the fixing unit, and a heat conduction unit disposed adjacent to a heated surface of the fixing unit. The fixing unit includes a first region not in contact with the sheet during heating of the sheet and a second region that is in contact with the heated sheet during heating of the sheet and has a temperature lower than the first region as a result of the contact with the sheet during the heating. The heat conduction unit is configured to transfer heat from the first region to the second region.

Abstract: A fixing device for an image forming apparatus has a tubular fixing member that has a lubricant-coated inner surface. A rotating member contacts an outer surface of the fixing member. A heater is on an inner surface side of the fixing member at a first position. A pressing member presses against the inner surface of the fixing member at a second position. The pressing member extends beyond the outer edges of the fixing member and includes first grooves in an outward facing surface that contacts the inner surface of fixing member. At least one first groove has end portion that extends beyond an outer edge of the fixing member, an inner portion inside the outer edges of the fixing member, and connecting portion connecting the two other portions. The connector portion is angled inward toward a center of the fixing member and crosses the outer edge of the fixing member.

Abstract: According to an embodiment, a heating device includes a cylindrical belt, a heater, a press roller, and a holder. The heater is disposed on an inner surface of the belt. The press roller rotates and is configured to contact an outer surface of the belt at a position opposite the heater to form a nip. The end portions of the press roller project by a first amount in a radial direction more than the central portion of the press roller. A holder has a first surface supporting the heater to face the cylindrical belt. The holder has a second surface that is opposite of the first surface with a center portion projecting in a direction orthogonal to the first surface more than the end portions of the second surface by a second projection amount that is greater than the first projection amount.
