Abstract: An image forming apparatus includes a recording head, a controller, and a correction processor. The controller determines a nozzle corresponding to an image to be printed, and causes the recording head to eject ink from the nozzle. The correction processor detects an abnormally ejecting nozzle out of the nozzles in the recording head, and designates the abnormally ejecting nozzle as a target nozzle, and performs correction processing based on a status of the target nozzle, to the image. The correction processor also adds the detected abnormally ejecting nozzle to history data, each time a detecting operation is performed, and selects a nozzle included in the history data as an additional target nozzle, out of the nozzles that have not been detected as the abnormally ejecting nozzle, through the current detecting operation, and adds the selected nozzle to the target nozzle.

Abstract: In the technology of the present disclosure, multiple nozzles included in a printing head are stably driven while disparity in the usage frequency of each nozzle is suppressed. The dot counter scans the digital halftone data in the X direction and performs accumulation-counting on the pixel value Ixy (the number of printing dots) of each pixel for each address y with the accumulation counter CntCum(y). The signal value Gxy of the corresponding pixel address (x, y) is obtained from the division pattern memory unit. The nozzle selection unit selects the nozzle to be used for forming a printing dot, based on the counted values of the accumulation counter CntCum and the signal value Gxy of the division pattern. Then, the address n of the nozzle memory corresponding to the selected nozzle to form a printing dot is determined.
