Abstract: An apparatus for determining a type of a recording medium is provided. A detection unit detects a characteristic value indicating a physical characteristic of a recording medium. A measurement unit measures a moisture content correlated with a moisture content of the recording medium. A determination unit determines the type of the recording medium based on the moisture content and the characteristic value. The determination unit may correct the characteristic value using the moisture content or correct a rule for determining the type of the recording medium using the moisture content unit, and determines the type of the recording medium in accordance with the corrected characteristic value or the corrected rule.

Abstract: Provided is an image heating apparatus comprising: a first rotating member; a second rotating member that forms a nip with the first rotating member so as to nip the recording material therebetween; a heater that heats the nip; a conductive sheet member that is disposed so as to overlap with a part of the heater; and a restricting member that restricts relative positions between the sheet member and the heater. The restricting member is configured so as to restrict a relative movement between the sheet member and the heater in a first direction, which is a direction where the sheet member overlaps with a part of the heater, and to allow the relative movement in a second direction which is perpendicular to the first direction. A reinforcing land, that joins the heater and the sheet member, is disposed in a position that is electrically isolated.
