Abstract
Abstract In a transfer-type image recording device utilizing a recording medium comprising a continuous-form recording sheet and a cut-form developing sheet, the former is arranged to be fed in a predetermined speed, coated with a plurality of photo and pressure sensitive microcapsules each containing a dye-precursor and a component to change the strength thereof when exposed to light. And the latter is designed to be coated with a developer material which is reactable with the dye-precursor. In the image recording device, a visible image is obtained by transferring an image having been formed on the recording sheet onto a surface of the developing sheet. A roller member for peeling off the microcapsules from a surface of the recording sheet after a transfer operation of an image is executed. Thus, any recognizable image on the recording sheet, for example, a visible negative image formed by the remained microcapsules, is erased after the visible image is obtained on the developing sheet.
