Liquid discharge head and recording device

A liquid discharge head, comprising:

• a discharge unit comprising a nozzle configured to discharge a droplet, a pressurizing chamber connected to the nozzle, and a pressurizer supplied with a first drive signal and configured to deform the pressurizing chamber;
• a dummy unit comprising a dummy pressurizing chamber and a dummy pressurizer supplied with a second drive signal and configured to deform the dummy pressurizing chamber;
• a discharge region that is a region where a plurality of the discharge units is disposed in one row;
• and
• a dummy region that is a region where one or more of the dummy units are disposed adjacent to the discharge region on an extended line of the one row of the discharge units,
• wherein the discharge region comprises a central region located at a center of the one row and an end portion region located adjacent to the dummy region at an end portion of the one row,
• the end portion region is a region where dots discharged based on the same first drive signal and formed on recording medium are greater in size than those discharged in the central region when the dummy unit is not driven, and
• during printing, the second drive signal is supplied to the dummy unit to drive the dummy unit while the first drive signal is being supplied to the discharge unit located in the end portion region and the discharge unit located in the end portion region is being driven.
