Abstract: PURPOSE: To provide an image recorder which can record at a high speed with a simple structure and has quick-drying properties, no stain at a front surface and no penetration to a rear surface. CONSTITUTION: The dispersion supply unit 4 of a printer 1 supplies a suitable quantity of dispersion 2 in which many colored solid particles charged with positive polarity are dispersed to the front surface of an insulating tape 3. The front surface of the tape 3 is coated with a material which has extremely strong hydrophilic property to the dispersion 2, and uniformly adhered with the dispersion 2 of sufficient quantity for printing. A tape driver 9 stepwisely drives the tape 3 in synchronization with the printing operation of the printer 1 in the direction of an arrow A. A particle forming unit 6 disposed at the downstream of the moving direction of the tape 3 applies a negative high voltage to an aggregate electrode 6a in contact with the rear surface of the tape 3 to aggregate the particles in the dispersion 2 to form a particle group 5a.  Further, a particle flying unit 7 disposed at the downstream applies a positive high voltage to a flying electrode 7a in contact with the rear surface of the tape 3 to give a flying force to the group 5a. The group 5a becomes a particle droplet 5b to be flown to an opposite negative electrode 7b to shoot a recording member 8, thereby forming a print dot.

Title: Current supply recording head
Inventor: MIMA SOICHIRO
IPC: B41J2/32
Filed: 1987-11-04
Abstract: PURPOSE:To always perform areal gradation recording in a stable dot shape, by constituting a current supply recording head of a plurality of conductors different in a temp. coefficient. CONSTITUTION:The surface temp. of the recording electrode 1 of a current supply recording head 5 rises along with the generation of heat and the electric resistances of the conductors A, B constituting the recording electrode 1 are respectively changed. When the temp. of the leading end of the recording electrode exceeds critical temp., the superconductive material of the conductor B is changed to a high resistance material at the part brought into contact with a transfer sheet 8. At this moment, the electric resistance of the conductor B rises at a stroke and the current flowing through the conductor B hearetofore avoids the conductor B to flow through the conductor A therearound and flows through a sheath in a direction 8b. At this time, the heat generating part of a resistant layer 8 spreads outwardly and the heat thereof passes through a conductive layer 7 to form the molten color material layer 6d of a color material layer 6. Therefore, the part rising to the temp. necessary for transfer in the color material layer 6 gradually spreads from 6c to 6d corresponding to a current supply time and, by controlling the current supply time, the areal gradation recording of the color material layer 6 becomes possible.
