摘要： A fixing device includes a heating member that heats a developer image on a recording medium; a controlling member that controls a surface temperature of the heating member by coming into contact with an outer circumferential surface of the heating member; a measuring member that measures, on a downstream of the controlling member and on an upstream of a pressing member in a rotation direction of the heating member, the surface temperature; and a supporting unit that causes the controlling member to come into contact with and be separated from the outer circumferential surface by rotating a supporting member around a rotation fulcrum. A distance between the rotation fulcrum and a contact position at which the controlling member comes into contact with the outer circumferential surface is longer than that between the rotation fulcrum and a measurement position at which the measuring member measures the surface temperature.

摘要： An image forming apparatus includes a transfer member, first transfer units, and second transfer units. Images of reference colors and other colors are transferred onto the transfer member being rotated. The first transfer units each transfer the image of a corresponding one of the reference colors. The second transfer units disposed upstream of the first transfer units in a rotational direction of the transfer member each transfer the image of a corresponding one of the other colors. The image of one of the reference colors is transferred by one of the first transfer units disposed most upstream. The other colors include at least one color of lightness lower than lightness of the one of the reference colors of the image transferred by the one of the transfer units. The highest-lightness image among the other colors is transferred by one of the second transfer units disposed most downstream.
