Abstract
In a fixing device, a fixed member is fixedly provided inside a loop formed by a belt, and is pressed against a pressing rotary member via the belt to form a nip portion between the pressing rotary member and the belt to nip a recording medium bearing a toner image. A heating member is fixedly, provided inside the loop formed by the belt to heat the belt. The heating member includes an opening opposing the pressing rotary member. A seal member covers the opening in the heating member to prevent a foreign substance from entering the heating member through the opening in the heating member. A reinforcement member is fixedly provided inside the heating member and pressed against the fixed member via the seal member to reinforce the fixed member.
