An image forming apparatus includes a reciprocally movable carriage, an image forming unit, a first drive source, a vibration suppressor, and a vibration-suppression controller. The reciprocally movable carriage moves in a main scan direction. The image forming unit is mounted on the carriage. The first drive source moves the carriage. The vibration suppressor suppresses vibration caused by movement of the carriage, and includes a vibration suppression member having a mass smaller than a mass of the carriage and a second drive source independent of the first drive source to move the vibration suppression member. The vibration-suppression controller drives the second drive source to cause the vibration suppressor to perform vibration suppression operation during at least one of an acceleration period and a deceleration period of the carriage, and stops movement of the vibration suppression member during a constant-speed period of the carriage.
