ABSTRACT:
An image forming apparatus, which performs recording by discharging ink onto a recording medium using a recording head that discharges the ink, includes a carriage that is mounted with the recording head and scans in a main scanning direction, a linear scale that is provided with graduations for detecting a position of the recording head mounted on the carriage and extends along the main scanning direction, a linear sensor that is fixed to the carriage and reads out the graduations on the linear scale by scanning in the main scanning direction on the linear scale together with the carriage, and an air guide that is arranged in a vicinity of the linear sensor in the main scanning direction and guides air moving toward the linear sensor as the carriage scans such that the air is directed away from the linear sensor. In the image recording apparatus, adhesion of ink mist to the linear sensor can be reduced.
