Abstract:
An image forming apparatus includes a carriage configured to travel with a recording head configured to eject liquid droplets being mounted thereon; a first encoder including a first encoder scale placed along a traveling direction of the carriage and a first encoder sensor configured to read the first encoder scale; an antiphase member configured to travel in opposite phase from the carriage; a second encoder including a second encoder scale placed along a traveling direction of the antiphase member and a second encoder sensor configured to read the second encoder scale; and a control part configured to control the travel of the carriage in accordance with the detection result of the first encoder and the detection result of the second encoder.
