Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 97 words
An ink jet recording method wherein an ink is discharged from an ink discharge opening in accordance with a discharging signal to effect recording, which comprises: driving an ink droplet volume discharging means to provide an ink droplet as discharged from the ink discharge opening in accordance with the discharging signal having a volume of no greater than 40 pl; and irradiating the discharged ink droplet with a laser to provide a temperature of the ink droplet at an ink deposition point on a recording medium to which the recording is effected of at least 60° C.
Claim 2
Dependent Claim 97 words
An ink jet recording method wherein an ink is discharged from an ink discharge opening in accordance with a discharging signal to effect recording, which comprises: driving an ink droplet volume discharging means to provide an ink droplet as discharged from the ink discharge opening in accordance with the discharging signal having a volume of no greater than 40 pl; and irradiating the discharged ink droplet with a laser to provide a temperature of the ink droplet at an ink deposition point on a recording medium to which the recording is effected of at least 60° C.
Claim 3
Dependent Claim 118 words
An ink jet recording method wherein an ink droplet is discharged from each of a plurality of ink discharge openings in accordance with a discharging signal to effect recording, which comprises: driving an ink droplet discharging means to provide an ink droplet volume as discharged from the ink discharge opening in accordance with the discharging signal for forming one picture element by superimposition of a plurality of the ink droplets, each said ink droplet having a volume of no greater than 40 pl; and adjusting the ink discharging means to provide a temperature of the discharged ink droplet at an ink deposition point on a recording medium to which the recording is effected of at least 60° C.
Claim 4
Dependent Claim 118 words
An ink jet recording method wherein an ink droplet is discharged from each of a plurality of ink discharge openings in accordance with a discharging signal to effect recording, which comprises: driving an ink droplet discharging means to provide an ink droplet volume as discharged from the ink discharge opening in accordance with the discharging signal for forming one picture element by superimposition of a plurality of the ink droplets, each said ink droplet having a volume of no greater than 40 pl; and adjusting the ink discharging means to provide a temperature of the discharged ink droplet at an ink deposition point on a recording medium to which the recording is effected of at least 60° C.
