摘要： An ink discharge device is provided including an ink, an ink discharge head, and a circulator. The ink discharge head includes a nozzle, an individual liquid chamber communicated with the nozzle, a flow-in channel, and a flow-out channel. The circulator circulates the ink by letting the ink flow into the individual liquid chamber via the flow-in channel and flow out from the individual liquid chamber via the flow-out channel. A flow rate of the circulated ink is 0.10 to 1.50 times a maximum dischargeable rate of the ink discharge head. A dynamic surface tension A of the ink at 25° C. is 34.0 mN/m or less when measured by a maximum bubble pressure method at a surface lifetime of 15 msec, and the dynamic surface tension A and a static surface tension B of the ink at 25° C. satisfy the following relation: 10.0(%)≤[(A−B)/(A+B)]×100≤19.0(%).

摘要： A head drive control unit generates and outputs a pulse formed of a first expansion waveform element to expand individual liquid chambers, a first contraction waveform element to contract the individual liquid chambers, a second expansion waveform element to expand the individual liquid chambers, and a second contraction waveform element to return the individual liquid chambers that have repeatedly expanded and contracted to an initial state. The first contraction waveform element serves as a waveform element that contracts the individual liquid chambers at a timing of resonance with a change in a pressure in the individual liquid chambers due to the first expansion waveform element. The second contraction waveform element serves as a waveform element that suppresses the change in the pressure in the individual liquid chambers.

摘要： An image forming apparatus includes: a liquid ejecting head including a nozzle that ejects a droplet and a pressure producing unit that produces pressure to pressurize a pressure chamber communicating with the nozzle; and a head drive controlling unit that provides a driving signal to the pressure producing unit. The head drive controlling unit outputs the driving signal including at least a first driving pulse and a second driving pulse to eject droplets and a residual vibration suppressing pulse to suppress residual vibration in the pressure chamber without ejecting a droplet. The residual vibration suppressing pulse is output at such a timing that the residual vibration suppressing pulse has an opposite phase to a composite vibration Vab that is formed by superposition of a meniscus vibration Va generated by droplet ejection with the first driving pulse and a meniscus vibration Vb generated by droplet ejection with the second driving pulse.
