CONSTITUTION:A cylindrical heating element 7 consisting of a resistor, etc. is fitted integrally onto an inner surface in the vicinity of an orifice 6 in a housing 2 constituting a head 1. On the other hand, a bypass duct 9 introducing ink from an ink tank 4 is formed on the upstream side of the heating element 7, the other end of the bypass duct is communicated with an ink chamber 5 on the downstream side of the heating element 7, and the bypass duct is constituted so that the downstream side of the heating element 7 is supplied with ink by negative pressure generated after the injection of ink. According to said constitution, a mechanism directly pressurizing a recording liquid is unnecessitated, and the title recording device can be miniaturized while a heating section after ejecting globules is filled rapidly with the recording liquid from the upstream side from the downstream side, thus largely increasing the speed of recording.
