Abstract
In a fixing device, a pressing member rotates in a predetermined direction of rotation. A flexible endless fixing member rotates in accordance with rotation of the pressing member. A nip formation member is provided inside a loop formed by the fixing member and pressed against the pressing member via the fixing member to form a nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. A first heat generator faces an inner circumferential surface of the fixing member at a position other than the nip to heat the fixing member. A second heat generator faces the inner circumferential surface of the fixing member at a position other than the nip to heat the fixing member, and is disposed adjacent to the first heat generator along the inner circumferential surface of the fixing member.
