摘要： In a jet recording method, a normally solid recording material is placed in a heat-melted state in a path defined by a nozzle leading to an ejection outlet and, in a recording step, is imparted with a thermal energy corresponding to a recording signal to generate a bubble, thus ejecting a droplet of the recording material out of the ejection outlet. As an improvement, prior to the recording step, the recording material is sucked or pressurized to be ejected out of the ejection outlet and, in the recording step, the bubble is communicated with ambience. As a result, the recording is started or resumed without discharge failure even after a long time of non-use or standing state.

The coloring material is a pigment, and, it contains a pigment particle having at least one ionic group bonded to a surface of the pigment particle directly or via another atomic group. The plurality of water-soluble organic solvents have a good medium or good mediums for the pigment and a poor medium or poor mediums for the pigment. The poor medium does not solvate perfectly or substantially the pigment. The ionic group undergoes perfectly or substantially no ionic dissociation in the poor medium. Also, among the respective Ka values of the plurality of water-soluble organic solvents as determined by the Bristow method, the Ka value of the poor medium is maximum.

摘要： In a jet recording method, a recording material is placed in a path defined by a nozzle leading to an ejection outlet, and then heated by actuating a heater disposed within the nozzle to generate a bubble within the recording material, thus ejecting a droplet of the recording material out of the ejection outlet under the action of the bubble to be attached onto recording paper. As improvement, the recording material is pre-heated by actuating the heater before the heating for generating the bubble, and the generated bubble is caused to communicate with ambience. As a result, the ejection of the recording material droplet is stabilized without causing splash or mist.
