摘要： An image forming apparatus includes a liquid discharge device and processing circuitry. The liquid discharge device includes at least one nozzle group, where N represents an integer, to discharge liquid. The processing circuitry causes the first nozzle group to discharge in a first scan, causes the second nozzle group to discharge in a second scan, and causes the N-th nozzle group to discharge in an N-th scan to form a complete image. The processing circuitry, with respect to an image completion rate indicating a rate of an image formed by each of the first nozzle group to the N-th nozzle group in the complete image, sets the image completion rate of a portion of the first nozzle group adjacent to the second nozzle group in the sub-scanning direction to be not higher than the image completion rate of any one of the second nozzle group to the N-th nozzle group.

摘要： A liquid discharge apparatus includes a liquid discharge head having at least one nozzle array including a plurality of nozzles lined in a nozzle array direction; a two-dimensional image sensor to capture an image formed by the liquid discharge head; and circuitry. The circuitry is configured to divide the nozzles into a plurality of nozzle units; form a pattern including a plurality of unit patterns with liquid discharged from the nozzle units, respectively; and detect a defective nozzle based on a captured image of each of the unit patterns. The unit patterns are arranged in a staggered manner. Each unit pattern is smaller in size than an image capture range of the two-dimensional image sensor. Each unit pattern includes a number of columns of lines extending in a direction perpendicular to the nozzle array direction, and the number of columns is not smaller than twice the number of nozzle arrays.
