摘要： An image processing method generates image data for use by an image forming apparatus which forms an image on a recording medium by ink dots formed by ejected ink drops. The image processing method includes the steps of judging an image portion and a background portion of the image, and adding image dots to the background portion adjacent to the image portion to fatten the image portion by a fattening process, depending on at least one of a character size of the image portion, a character type of the image portion, a resolution of the image portion, and a color of the background portion.

摘要： An image forming apparatus is disclosed that includes a recording head including a nozzle from which liquid droplets are ejected, a pressure chamber communicating with the nozzle and containing liquid, and a pressure generation part changing the volume of the pressure chamber; and a drive signal generation part generating a drive signal including multiple drive pulses and causing the pressure generation part to operate so that the liquid droplets are ejected. The drive signal generated by the drive signal generation part includes, within a single print cycle, a resonant drive pulse causing a first one of the liquid droplets to be ejected using the natural vibration period of the pressure chamber, a non-resonant drive pulse causing a second one of the liquid droplets to be ejected without using the natural vibration period of the pressure chamber, and a slight drive pulse prevented from causing the ink droplets to be ejected.

摘要： An image forming apparatus includes a recording head, a head driving control circuit, and a dummy ejection control circuit. The dummy ejection control circuit controls a first dummy ejection operation to eject droplets to a non-image-forming area per a constant length of a continuous medium and second dummy ejection operation to eject droplets not contributing to image formation to an image forming area. The head driving control circuit applies a first non-ejection pulse to pressure generators corresponding to a non-ejection nozzle of the plurality of nozzles to vibrate a meniscus of liquid in the non-ejection nozzle without ejecting liquid droplets, and applies a second non-ejection pulse, which vibrates the meniscus of liquid greater than the first non-ejection pulse, to pressure generators corresponding to non-ejection nozzles of the plurality of nozzles to vibrate a meniscus of liquid in the non-image-forming area.

摘要： An image forming apparatus includes a recording head, a head driving control unit, and a dummy ejection control unit. The dummy ejection control unit controls first dummy ejection operation to eject droplets to a continuous medium per a constant length and second dummy ejection operation to eject droplets not contributing to image formation to an image formation area. In the first dummy ejection operation, the head driving control unit applies a first non ejection pulse to a pressure generator corresponding to a non ejection nozzle. In the second dummy ejection operation, the head driving control unit applies a second non ejection pulse to the pressure generator corresponding to the non ejection nozzle. When the second non ejection pulse is applied, an amplitude or number of vibrations of a meniscus of liquid in the non ejection nozzle is greater than when the first non ejection pulse is applied.
