Title:
画像形成装置及び液滴吐出制御プログラム
Document Type and Number:
Japanese Patent JP7476576
Kind Code:
B2
Abstract:
An image forming apparatus includes: a piezoelectric element with a common electrode on one side and an individual electrode on another side; a nozzle; and circuitry. The circuitry selects one from drive signals and supplies the one drive signal to the piezoelectric element via the individual electrode, to discharge a droplet through the nozzle to form an image. Each drive signal includes waveform pulses including a main pulse that rises in a slope shape during a rising time and finishes rising at an end time. The circuitry generates the drive signals so that the end time of a less influential drive signal other than a most influential drive signal falls within a range of the rising time of the main pulse of the most influential drive signal; selects the one drive signal based on an image to be formed; and supplies the one drive signal to the piezoelectric element.
