    摘要: A fixing device includes a heat conductor disposed opposite an inner circumferential surface of an endless belt to heat the endless belt. A nip formation pad is disposed opposite the inner circumferential surface of the endless belt and presses the endless belt against a pressing rotary body to form a fixing nip between the endless belt and the pressing rotary body through which a recording medium bearing a toner image is conveyed. A support is disposed opposite an inner circumferential surface of the heat conductor and contacts an abutment face of the nip formation pad to support the nip formation pad against pressure from the pressing rotary body. A heat insulator is interposed between the heater and the nip formation pad and the support to shield the nip formation pad and the support from the heater.

    摘要: A fixing device includes a rotary fixing member, a counter member to contact the rotary fixing member, a first heater to heat the rotary fixing member, a driving unit to rotate the rotary fixing member, a temperature detector to detect a temperature of the rotary fixing member, and a contact-and-separation unit to switch between contact and separation states of the rotary fixing member relative to the counter member. In a temperature-raising operation, the driving unit causes the rotary fixing member to rotate when the temperature detector detects that the temperature of the rotary fixing member has reached a first setting temperature. The contact-and-separation unit causes the rotary fixing member in rotation and the counter member to contact each other when the temperature detector detects that the temperature of the rotary fixing member has reached a second setting temperature that is higher than the first setting temperature.

The drive train transmits a driving force of the drive source to a driven member. The plurality of drive transmitters include a first group of the drive transmitters and a second group of the drive transmitters. The drive source and the first group of the drive transmitters together serve as an integrated unit attached to one side of a facing member facing a side panel of an image forming apparatus. The integrated unit includes a positioning object. The second group of the drive transmitters is supported by a shaft disposed on another side of the facing member. The positioning member includes a positioning portion with which the positioning object is engaged on the one side or said another side of the facing member.

    摘要: A fixing device fixes a toner image on a recording medium transported to a fixing nip by applying pressure and heat to the recording medium. The fixing device includes an endless belt formed into a loop with both ends bonded together, the belt accommodating a heat source inside thereof, a pressing roller rotating in contact with the endless belt forming the fixing nip between the endless belt and the pressing roller, and a fixed member provided inside a loop of the endless belt to press the endless belt against a pressing roller. A reinforcing member is bonded to the fixed member inside the loop of the endless belt to reinforce the fixed member. A reflector is provided to reflect light emitted from the heat source toward the inner circumferential surface of the endless belt. The reflector is held on the reinforcing member by either plastically or elastically deforming by itself.

    摘要: A fixing unit includes an endless belt unit accommodating a heat source, a pressure roller to rotate in contact with the fixing belt unit forming a pressure border therebetween, and a heat transfer member heated by the heat source to heat the fixing belt unit. The heat transfer member is secured inside an inner circumferential surface of the fixing belt unit and supports the fixing belt unit. A fixed member is secured inside the inner circumferential surface of the fixing belt unit and is pressed against the pressure roller via the fixing belt unit. The heat transfer member has at least one convex portion partially formed in an outer circumferential surface of the heat transfer member in a rotational direction of the fixing belt unit and a longitudinal direction of the heat transfer member to narrow a gap formed between the heat transfer member and the fixing belt unit.

    摘要: A fixing device includes an endless belt and an opposed rotary body contacting an outer circumferential surface of the belt. A nip formation pad contacting a first part of an inner circumferential surface of the belt presses against the opposed rotary body via the belt to form a fixing nip between the belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A heat conductor disposed opposite a second part of the inner circumferential surface of the belt not contacted by the nip formation pad is interposed between a heater and the belt to conduct heat from the heater to the belt. A reflector disposed inside the loop formed by the belt reflects light from the heater toward the heat conductor. The reflector and the heat conductor surround the heater.
