Abstract: A fixing apparatus includes: a first rotating body that contacts a sheet for printing and heats the sheet; a second rotating body that rotates while pressing the first rotating body; a motor that rotates the first rotating body; and a hardware processor that determines whether an abnormal noise occurs on the basis of a plurality of condition values including a torque value of the motor, wherein the hardware processor performs abnormal noise prevention control that increases the rotation of the first rotating body or weakens pressing applied by the second rotating body to the first rotating body in a case where it is determined that the abnormal noise occurs.

Abstract: A fixing device includes: a fixing belt of an endless shape wound to pass over a heating-side member and a nip forming member; and a pressing roller driven to rotate in a state of being brought into tight contact with the nip forming member through the fixing belt, wherein a toner image is fixed to a recording medium at a nip portion at which the fixing belt and the pressing roller are brought into tight contact with each other by causing the pressing roller to be in tight contact with the fixing belt and driving the pressing roller to rotate, a guide member guiding the fixing belt to a space between the nip forming member and the heating-side member is disposed to be separate from the nip forming member, and a sliding member is disposed at least in a contact portion between the nip forming member and the fixing belt.

Abstract: A fusing apparatus includes: a rotating endless belt; a pressing member pressing the belt from an inside of the belt; and a roller forming the fusing nip between the roller and the belt by pressing, from an outside of the belt, a position where the belt faces the pressing member, wherein a surface of the pressing member facing the roller via the belt includes: plane surface, and a curved surface adjacent to the plane surface at a downstream-side end in a conveying direction of the storage medium of the plane surface, and when viewed from a cross-section orthogonal to a central axis of the roller, an upstream-side end of the conveying direction of the plane surface is away from a straight line passing through the central axis of the pressure roller and parallel to the conveying direction, farther than the downstream-side end in the conveying direction of the plane surface.
