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.

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, in the recording step, the bubble is caused to communicate with ambience, and the droplet is ejected in a diameter d (.mu.m) and at an average speed v (m/sec) satisfying: 10.ltoreq.d.ltoreq.60 and 7.ltoreq.v.ltoreq.20. As a result, the droplet is deposited on a recording medium without pileup or scattering.

A normally solid recording material is heat-melted in a path defined by a nozzle leading to an ejection outlet and is imparted with a thermal energy from a heater corresponding to a recording signal to generate a bubble. As a result, a droplet of the recording material is ejected out of the ejection outlet under the action of the bubble while the bubble is caused to communicate with ambience. The normally solid recording material preferably contains a colorant, a first heat-fusible solid substance having a melting point Tm of 36.degree.-150.degree. C. and a boiling point Tb of 150.degree.-370.degree. C., and a second heat-fusible solid substance having a melting point Tm and a solidifying point Tf satisfying a relationship of Tm-Tf.ltoreq.30.degree. C. The distance between the heater and the ejection outlet, the sectional size of the nozzle and the thermal energy imparted by the heater are controlled to cause the bubble to communicate with ambience.

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.
摘要:
A normally solid recording material for use in a jet recording method wherein a recording material is ejected through an ejection outlet for recording, is composed from a heat-fusible solid vehicle and a dye compound. The dye compound is formed as a salt of a dye having a group of --SO.sub.3 M or --COOM (wherein M denotes an alkali metal) and a linear alkylamine. As a result, the dye compound is provided with an increased molecular length, because of which the sublimability of the dye compound is suppressed to provide the recording material with improved fixability and freeness from a bleeding phenomenon that the color of a recorded image is transferred to another sheet contacting the image.

In a printing apparatus using a plurality of heating elements as printing elements, there are provided CCD elements for storing electric charges whose quantity correspond to temperatures in correspondence to each of the printing elements, and for sequentially transferring these electric charges. As a printing head driving apparatus, an analog shift register having a series of CCD elements is employed in order to perform data transfer operation, data alignment, and driving operations of the respective printing elements. Also, the above-described CCD elements are commonly used with CCD elements for storing and transferring temperature data. As a result, a compact printing apparatus can be made while suppressing shading in images caused by temperature increasing due to the driving operation of the printing elements.
