An image reading apparatus includes a cover, a reading device including a light source and a sensor, and a control device including circuitry. The circuitry acquires first data with the light source turned off, acquires second data with the light source turned on, calculates a first evaluation value for each of plural locations of the first data, calculates a second evaluation value for each of plural locations of the second data, determines an open or closed state of the cover based on the first evaluation value and the second evaluation value, determines that the cover is open when at least one of a determination result based on the first evaluation value or a determination result based on the second evaluation value indicates the open state of the cover, and determines that the cover is closed when the two determination results both indicate the closed state of the cover.
