An image reading apparatus includes an image reading unit, a condensation determination circuit, a condensation removal unit, a time measurement circuit, and a shortest determination circuit. The condensation removal unit executes a condensation removal in accordance with a specific condensation removal pattern among a plurality of condensation removal patterns for heating the condensation occurrence target portion when an occurrence of condensation is determined. The time measurement circuit measures a condensation removal time taken to complete the condensation removal of the specific condensation removal pattern. The shortest determination circuit determines the condensation removal pattern having a shortest of the condensation removal time among the plurality of the condensation removal patterns as a shortest pattern, and causes the condensation removal unit to execute the condensation removal in accordance with the shortest pattern when the condensation determination circuit determines that a condensatio
