Patent ID: 8727498

Claim:
A drive circuit for an inkjet recording head comprising: a plurality of electrically capacitive actuator elements provided for a plurality of nozzles, and configured to drive the nozzles to eject ink therefrom; a drive signal source configured to output a drive signal for driving the actuator elements; a plurality of switching elements connected to the respective actuator elements to separately drive the actuator elements, and configured to selectively apply the output drive signal to the actuator elements; and a plurality of return resistances provided for the respective actuator elements and connected to low potential sides of the actuator elements, each of the return resistances having a resistance value adjusted based on the length of a wiring line between the corresponding one of the actuator elements and the drive signal source, a resistance value of a first return resistance of the return resistances being greater than a resistance value of a second return resistance of the return resistances.
