To provide an image recording method and apparatus that can record and display
an image of free pattern without forming the complex wirings in an electrochromic
material, and to reduce the manufacturing costs of the image recording apparatus
employing the EC material.
A recording sheet 7 having a coloring layer made of an electrochromic
material
and an electrolytic layer with an increasing electrical conductivity in a specific
temperature range is employed, and a recording head 13 with a plurality
of heating elements arranged in a linear direction is moved relative to the surface
of the recording sheet 7 in the direction orthogonal to the linear direction
while at the same time a voltage is applied to the front and back faces of the
recording sheet 7, thereby selectively heating the heating elements 11.
Thereby, a coloring reaction is caused only in a part where heat is applied by
the heating elements of the recording sheet 7 and voltage is applied to
form an image on the recording sheet 7.
