Fixing device and image forming apparatus

A fixing device comprising:

• a first belt configured to contact a developer image on a recording medium;
• a second belt configured to sandwich the recording medium with the first belt and hence form a nip region extending in a transport direction of the recording medium;
• a rotational body that is provided inside the first belt in a region at a downstream side in the transport direction of the nip region,
• wherein the rotational body is configured to rotate and turn the first belt;
• a pressing member that is provided inside the second belt,
• wherein the pressing member is configured to press the second belt toward the rotational body;
• and
• a heating unit that is provided inside the first belt in a region at an upstream side in the transport direction of the nip region in a non-contact manner with respect to the first belt, wherein the heating unit is configured to heat the developer image on the recording medium,
• wherein the heating unit has a halogen lamp and a reflecting surface configured to reflect light of the halogen lamp toward the nip region,
• wherein the fixing device further comprises a winding member including the reflecting surface, a portion of the first belt being wound around the winding member, and
• wherein the winding member includes a support portion that supports the first belt at a position located downstream of the heating unit and located upstream of the rotational body in the transport direction.
