ABSTRACT:
Disclosed is an imaging device wherein a latent image is formed by projecting an optical image on a photo and pressure sensitive recording sheet, on which a plurality of microcapsules enveloping photo-hardenable resins and chromogenic materials therein are coated, and a visible image is developed on a transfer sheet by pressurizing the recording sheet in superposed state with the transfer sheet, the transfer sheet being coated with color-developing agents which react with the chromogenic materials to develop the visible image.
The disclosed imaging device comprises an exposing unit for exposing the recording sheet, which is arranged to extend over the entire width of the recording sheet, and a pressing unit for pressing the recording sheet and the transfer sheet in superposed state.
