Abstract:
1. An image heating apparatus, comprising: first and second rotational bodies that form a nip portion while being in pressure contact with each other; a heating unit that heats the first rotating body to heat an image formed on a recording sheet conveyed to the nip portion; a pressure-contact mechanism that makes the first and second rotational bodies come in pressure contact to form the nip portion; a temperature sensor that detects the temperature of the first rotating body; a driving mechanism that rotationally drives either one of the rotating bodies among the first and second rotational bodies; and a control unit that executes a long grain feed mode of conveying a long grain recording sheet whose grain direction is in parallel with a conveying direction of the recording sheet and a short grain feed mode of conveying a short grain recording sheet whose grain direction is orthogonal to the conveying direction of the recording sheet, the control unit changing, in accordance to the long grain feed mode and the short grain feed mode, the temperature of the first rotating body set by the heating unit and setting of at least either one changeable setting among settings of the pressure-contact mechanism and the driving mechanism configured such that the setting of at least one of them is changeable.
