HEATING DISCHARGE TYPE PRINTING HEAD AND ITS DRIVE METHOD

摘要

Provided is a heating discharge type printing head capable of controlling an ion generation amount by detecting a temperature in the vicinity of a discharge electrode and controlling heating by heating means according to the temperature. The heating discharge type printing head includes a discharge unit having a discharge electrode having an electron emission portion and a heating unit for selectively heating the discharge electrode. The discharge unit or the heating unit has a temperature detection element.
