Abstract
A fixing device includes a fixing belt, a pressuring member, a heat source and a nip member. The fixing belt is arranged rotatably. The pressuring member is arranged rotatably to come into pressure contact with the fixing belt so as to form a fixing nip. The heat source is arranged at the inside in a radial direction of the fixing belt to radiate a radiant heat. The nip member is arranged so as to sandwich the fixing belt between the nip member and the pressuring member. The heat source, the fixing belt and the nip member are arranged so that the radiant heat radiated from the heat source reaches directly an inner circumference face of the fixing belt and the nip member.

A fixing device comprising:
- a fixing belt arranged rotatably;
- a pressuring member arranged rotatably to come into pressure contact with the fixing belt so as to form a fixing nip;
- a heat source arranged at the inside in a radial direction of the fixing belt to radiate a radiant heat;
- and
- a nip member arranged so as to sandwich the fixing belt between the nip member and the pressuring member,
- wherein the heat source, the fixing belt and the nip member are arranged so that the radiant heat radiated from the heat source reaches directly an inner circumference face of the fixing belt and the nip member, and
- the fixing device further comprising:
- a supporting member supporting the nip member,
- wherein the nip member includes:
- a radiated part which the radiant heat radiated from the heat source reaches directly;
- and
- a nip part connected to the radiated part, formed in a body with the radiated part and arranged so as to sandwich the fixing belt between the nip part and the pressuring member,
- the radiated part is arranged so as to partition the heat source from the supporting member.
