Abstract
Abstract In a method of and apparatus for adhesive transfer, an image receiving web comprising a belt-shaped, release agent coated paper and a plurality of transfer sheets having adhesive surfaces and put side by side on the release agent coated paper in the longitudinal direction thereof is used. The transfer sheets are separated one after another from the release agent coated paper, and each separated transfer sheet is wound around a transfer roller with the adhesive surface facing out. The transfer roller is moved to contact a photosensitive material drum carrying a toner image formed thereon, and the toner image is transferred from the photosensitive material drum to the adhesive surface of the transfer sheet while the transfer roller and the photosensitive material drum are rotated. The transfer roller is then moved to contact a push roller, and a supporting sheet is passed together with the transfer sheet between the transfer roller and the push roller, thereby to adhere the transfer sheet to the supporting sheet.

Claim 1
Independent Claim
206 words
An adhesive transfer method comprising the steps of: (i) separating a transfer sheet, which has been formed in a predetermined shape in advance and is provided with an adhesive surface and which is adhered to a release agent coated paper, from said release agent coated paper, associating said sheet with a transfer roller and winding said transfer sheet around the transfer roller with said adhesive surface facing out, (ii) contacting said transfer roller under pressure with a photosensitive material drum, which carries a toner image formed on its surface, by movement of said transfer roller with respect to said photosensitive material drum, and transferring said toner image from said photosensitive material drum to said adhesive surface of said transfer sheet while rotating said transfer roller and said photosensitive material drum, and (iii) thereafter moving said transfer roller away from said photosensitive material drum by movement of said transfer roller with respect to said photosensitive material drum, contacting said transfer roller with a push roller under pressure by movement of said transfer roller with respect to said push roller, and passing a supporting sheet together with said transfer sheet between said transfer roller and said push roller, thereby to adhere said transfer sheet to said supporting sheet.
