Abstract
A fixing device comprises: a heating rotary member and a pressurizing rotary member, which form a nip, and guiding members for guiding a recording sheet that has passed through the nip. In a cross-section perpendicular to a rotation axis of the heating rotary member, La connects axial centers of two rotary members, Lb is perpendicular to La, P is on a guiding surface of one of the guiding members and horizontally closer to the pressurizing rotary member than any other points thereon, said one of the guiding members being closer to the heating rotary member than the other, Lc passes through P and is tangent to an outer circumference of the heating rotary member near the nip, and D is a P-La distance. Here, heating rotary member diameter×1.6≦D<heating rotary member diameter×2.4. Above the nip, Lc leans further toward the heating rotary member than Lb, and 2.2°≦angle between Lc and Lb<6.5°.
