HEATING DISCHARGE TYPE PRINTHEAD AND IMAGE-FORMING DEVICE INCLUDING THE SAME

摘要

A heating discharge type printhead with high quality and excellent practicability is provided in which discharge from the discharge electrodes can be controlled simply and infallibly by selectively heating discharge electrodes using a heating means provided apart from the discharge electrodes, a simplified configuration provides excellent mass-productivity and reliability, the design is highly flexible without manufacture restrictions on the shape and arrangement of the discharge electrodes, and the image resolution and recording rate can be improved with the ease of high-density mounting. The heating discharge type printhead which controls discharge from discharge electrodes by controlling the temperature of the discharge electrodes to which a discharge-controlling voltage is applied comprises a discharger having the discharge electrodes and a heating means which is provided apart from the discharger and heats the discharge electrodes.
