Title: Image processing apparatus, image processing method and computer-readable recording medium of image processing method

Abstract: An image forming apparatus includes an image process control unit processing an image data and generating a control signal, and a drive pattern generation unit to generate a drive pattern to drive a recording head, based on the control signal, the drive pattern generation unit generating at least a first drive pattern and a second drive pattern which is different from the first drive pattern. The drive pattern generation unit sets a reference potential of the second drive pattern as a target reference potential and applying a pattern end of the first drive pattern to one of a pull-up pattern and a pull-down pattern operation before the second drive pattern is performed, wherein the drive pattern generation unit generates one of the pull-up pattern and the pull-down pattern based on a slope value obtained by comparing the target reference potential and the end potential.
