Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• an ejection portion having a nozzle for ejecting a liquid, a pressure chamber communicating with the nozzle, and a piezoelectric element that is configured to be driven to generate a pressure fluctuation in the liquid in the pressure chamber in response to a supplied drive signal;
• a drive signal generation circuit that is configured to generate the drive signal;
• an acquisition portion that is configured to acquire viscosity information indicating a viscosity of the liquid;
• and
• a control portion that is configured to control an operation of the drive signal generation circuit, wherein
• the drive signal includes an ejection pulse that supplies to the piezoelectric element when a droplet is ejected from the nozzle,
• the ejection pulse has
• a first contraction element that changes in potential by a first potential change amount to contract the pressure chamber,
• a first contraction maintaining element that is coupled to a terminal end of the first contraction element and maintains a terminal potential of the first contraction element, and
• a second contraction element that is coupled to a terminal end of the first contraction maintaining element and changes in potential by a second potential change amount to contract the pressure chamber,
• when the viscosity indicated by the viscosity information is a first viscosity, a ratio of the first potential change amount to the second potential change amount is a first value, and
• when the viscosity indicated by the viscosity information is a second viscosity higher than the first viscosity, the ratio of the first potential change amount to the second potential change amount is a second value smaller than the first value.
