Abstract
An image forming apparatus includes a controller configured to adjust ink ejection amounts from nozzles in a downstream nozzle array on a basis of a bypassing air flow degree. The bypassing air flow degree is calculated based on an ejection density of ink ejected from nozzles in an upstream nozzle array on a recording medium and indicates a generation degree of a bypassing air flow generated when a transfer air flow generated by transfer of the recording medium bypasses a self-generated air flow generated by ink ejected from the nozzles in the upstream nozzle array. The downstream nozzle array is a nozzle array located downstream in a transfer direction among a plurality of nozzle arrays. The upstream nozzle array is a nozzle array located upstream in the transfer direction among the plurality of nozzle arrays.
