Abstract
An image forming apparatus includes a rotational conveying unit for conveying a recording medium by rotating about a rotational axis. A head unit includes n nozzle rows in a conveying direction perpendicular to an axial direction parallel to the rotational axis. Each of the n nozzle rows includes nozzles aligned as a nozzle row in the axial direction. Each n nozzle row is arranged at a distance of dto d(n−1) from a predetermined reference nozzle row. A circuit outputs a rotational amount detection signal, and a conveying amount detection signal, and generates a discharge synchronization signal based on the detected rotational amount detection signal and the detected conveying amount detection signal, then generates a nozzle row timing signal based on the distance of the dto d(n−) and the discharge synchronization signal, and generates discharge data based on the discharge synchronization signal and the nozzle row timing signal.
