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: An image forming apparatus includes an acquiring unit configured to acquire atmosphere pressure in the installation place of the image forming apparatus, photoconductors, light sources configured to radiate laser light, and a polygon mirror configured to be rotatable. The polygon mirror exposes the photoconductors by reflecting the laser light toward the photoconductors while rotating. The image forming apparatus further includes a control device configured to control rotation of the polygon mirror. The control device outputs an enable signal for allowing the image forming apparatus to perform printing, if rotation of the polygon mirror is stabilized after start of the rotation, and advances the timing of outputting the enable signal as the atmosphere pressure increases.
