Abstract: An image reading apparatus includes: a movable body configured to illuminate a document with light; and an apparatus body configured to wirelessly transmit power to the movable body, wherein the movable body includes receiver coils, and a feed circuit in which the receiver coils uses receiving power to supply power to a load, the apparatus body includes transmitter coils placed along a track of the receiver coils, the transmitter coils and the receiver coils are placed such that power supply efficiency of any receiver coil with the transmitter coil placed along the track of the receiver coil fluctuates, and power supply efficiency related to one receiver coil increases at a position where power supply efficiency related to the other receiver coil drops, and the feed circuit supplies power sequentially using the receiving power of the receiver coil whose power supply efficiency is increased to highest among the receiver coils.

Abstract: A fixing device includes: a plurality of heating units which individually heat a plurality of areas of a fixing member; an acquisition unit which acquires information on an image forming range and a non-image forming range of the recording sheet for each of the plurality of divided heating areas; and a control unit which performs first control for controlling the corresponding heating unit such that a contact portion of the image forming range of the recording sheet has a target fixing temperature when the image forming range contacts the fixing member at the contact portion of the image forming range, and second control for controlling the corresponding heating unit such that a contact portion of the non-image forming range of the recording sheet has a temperature lower than the fixing temperature when the non-image forming range contacts the fixing member at the contact portion of the non-image forming range.
