画像形成装置
Document Type and Number:
Japanese Patent JP5117026
Kind Code:
B2
Abstract:
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.
