Abstract:
1. An image forming apparatus comprising: a dot former including a plurality of dot forming elements arranged along an array direction for ejecting droplets to form dots of at least two sizes on a recording medium; a dot formation controller for controlling the dot former based on a control signal supplied to the dot formation controller, to form the dots successively at a plurality of times to generate image arrays along the array direction while the dot former and the recording medium are being moved relatively to each other; and a signal converter for converting an input image signal into the control signal supplied to the dot formation controller such that if the dots formed along the array direction are classified into a plurality of groups depending on the plurality of times, an existing ratio of dots of a smaller one of the at least two sizes is higher for one of the groups of an earlier time of the times.
