Abstract: A fixing device includes a first fixing member, a second fixing member, a pressing member, and a heating device. The first fixing member is in an ungrounded state and comes into contact with a toner image on a sheet. The second fixing member is arranged opposite the first fixing member. The pressing member presses the first fixing member against the second fixing member so as to form, at the contact portion between the first fixing member and the second fixing member, a nip portion through which the sheet passes. The heating device heats the first fixing member.

Abstract: The fixing device includes a fixing member, a pressing member, and a heat source. The fixing member heats toner on a medium. The pressing member forms a pressing area with the fixing member and presses the toner. The heat source is provided corresponding to the pressing area across the fixing member and heats the fixing member. The heat source includes a heat insulation layer and a heating and contacting part. The heat insulation layer is laminated on a base material and has a convex part that protrudes toward the fixing member. The heating and contacting part is laminated on the heat insulation layer that has the convex part and contacts to an inner surface of the fixing member so as to heat the fixing member. The convex part protrudes the heating and contacting part laminated thereon toward the fixing member so as to maximize pressure in the pressing area.

Abstract: A fixing device includes a heating belt, a heat source, a pressuring body, a pressing member and a sheet member. The heating belt is endless and heats a medium while being circulated. The heat source supplies heat to the heating belt. The pressuring body forms a nip with the heating belt, rotates so as to circulate the heating belt and presses the medium with the heating belt. The pressing member is disposed inside the heating belt and presses the heating belt against the pressuring body at the nip. The sheet member is held between the heating belt and the pressing member, attached to the pressing member at a center side portion and both end side portions in a longitudinal direction of the sheet member and has a heat shrinkable property. The both end side portions are shiftable in the longitudinal direction greater than the center side portion.

Abstract: A fixing device fixing an image on a recording medium includes a fixing belt rotatable around a first rotation axis, a pressuring member, a heat source body and a cover member. The pressuring member forms a nip part pressuring and making the recording medium pass through with the fixing belt. The heat source body is arranged inside the fixing belt and heats the fixing belt by emitting radiant heat. The cover member is arranged between the fixing belt and the heat source body and covers the heat source body. The nip part has a passing area where the recording medium passes through and a non-passing area outside the passing area in an axial direction. The cover member covers a part of the heat source body corresponding to the non-passing area and includes through holes formed so as to adjust surface temperature of the heat source body.

Abstract: A temperature detection section is disposed opposite to a heater so as to be out of contact with the heater, and detects a temperature of the heating element. A spacer is disposed so that the heater and the temperature detection section are out of contact with each other. The spacer includes a separator that separates the temperature detection section from the heater and that has a gap through which the heat is transferred from the heater to the temperature detection section and that melts upon the temperature of the heating element increasing to a specific temperature or higher. The separator after melting fills the gap.
