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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
An adhesive transfer apparatus comprising: (i) a photosensitive material drum, (ii) a toner image forming means for forming a toner image on said photosensitive material drum, (iii) a push roller, (iv) a supporting sheet conveyance means for conveying a supporting sheet toward said push roller, (v) a separation means for 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, and (vi) a transfer roller which is moveable with respect to said photosensitive material drum and said push roller so that said transfer roller takes a first position spaced away from both said photosensitive material drum and said push roller, a second position contacting said photosensitive material drum alone under pressure, and a third position contacting said push roller alone under pressure, winds up said transfer sheet separated by said separation means with said adhesive surface facing out at said first position, transfers said toner image from said photosensitive material drum to said adhesive surface of said transfer sheet at said second position, and adheres said transfer sheet carrying said toner image transferred thereonto and said supporting sheet conveyed by said supporting sheet conveyance means to each other at said third position.
Claim 2
Dependent Claim
219 words
An adhesive transfer apparatus comprising: (i) a photosensitive material drum, (ii) a toner image forming means for forming a toner image on said photosensitive material drum, (iii) a push roller, (iv) a supporting sheet conveyance means for conveying a supporting sheet toward said push roller, (v) a separation means for 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, and (vi) a transfer roller which is moveable with respect to said photosensitive material drum and said push roller so that said transfer roller takes a first position spaced away from both said photosensitive material drum and said push roller, a second position contacting said photosensitive material drum alone under pressure, and a third position contacting said push roller alone under pressure, winds up said transfer sheet separated by said separation means with said adhesive surface facing out at said first position, transfers said toner image from said photosensitive material drum to said adhesive surface of said transfer sheet at said second position, and adheres said transfer sheet carrying said toner image transferred thereonto and said supporting sheet conveyed by said supporting sheet conveyance means to each other at said third position.
