This is a means for applying the developer toner 22 to the surface. The support 26 coated with the color developer is sent out along the conveyance 20, and is pressure developed together with the capsule sheet 7 by the pressure roller 27, thereby destroying the uncured capsules and developing color. The colored support] 7 is outputted from the outlet 28.

The operation of the image recording apparatus configured as described above will be explained. The capsule sheet 7 sent out from the delivery roller 5 is placed in the first darkroom 3 by light source lamps 8Y, 8M, 8.

nm, 650 nm, and magenta and cyan microcapsules are selectively cured. The third portion of the first darkroom is a basic exposure apparatus which is described in detail in the above-mentioned Japanese Patent Application Laid-Open No. 62-204277, and its explanation will be omitted here.

The capsule sheet 7 subjected to basic exposure in the first darkroom 3 is sent to the second darkroom 4. A color CRT 9 is provided in the second darkroom 4, and red pixels, green pixels, and blue pixels are respectively displayed in accordance with image signals for recording color images. electron gun 1
The deflection angle of the electron beam 11 emitted from 0 is controlled by the deflection coil 12, and the amount of electrons is controlled by a drive circuit (not shown), so that red pixels of the color image to be recorded appear on the phosphor 13R. One line out of a large number of scanning lines constituted by is sequentially displayed in accordance with an image signal SG supplied from an image signal generator (not shown).

The color developer toner 22 is conveyed onto the application roller 24 by the replenishment roller 23, and is positively charged by about 10 μc/g due to frictional charging there. The application roller 24
is grounded, and the opposing rollers 25 facing each other with the support body 26 in between are heated to -1 to -2 k by direct current (not shown).
When the potential is maintained at about V, the developer toner 22 is electrostatically attracted toward the opposing roller, and can be applied to the support 17. Further, the support body 26 coated with the color developer moves along the conveyance path 20 toward the developing section. The support 26 coated with a color developer and the capsule sheet 7 on which a latent image has been formed pass through a pressure roller 27 to destroy the microcapsules that have not been photocured, and the dye precursor contained therein reacts with the color developer. This will cause color development. The colored support 17 is outputted from the paper outlet 28. In this example, a method of applying a powdered color developer using electrostatic force was used as a means for applying a color developer to a support and obtaining a color developing medium, but the method is not limited to this, and for example, It is also possible to use a method of obtaining a color developing medium by spraying a liquid color developer onto a medium and drying it.
