A method of manufacturing a transfer sheet for transfer printing a pictorial pattern on a printing workpiece, the method comprising: providing a first sheet, the first sheet having: a first substrate layer, a first release layer on the first substrate layer, a resin layer on the first release layer, and a first porous resin layer on the resin layer; providing a second sheet, the second sheet having: a second substrate layer, a second release layer on the second substrate layer, an adhesive layer on the second release layer, and a second porous resin layer on the adhesive layer; forming an ink/resin toner layer (7,8) in the form of a pictorial pattern by printing on the first porous resin layer of the first sheet or the second porous resin layer of the second sheet by using an electronic image forming apparatus; after forming the ink/resin toner layer (7,8), superimposing the first sheet and the second sheet with the first porous resin layer and the second porous resin layer facing each other with the ink/resin toner layer (7,8) interposed therebetween; after superimposing the first sheet and the second sheet, adhering the first sheet and the second sheet via the ink/resin toner layer (7,8) by thermally pressing the two sheets; after thermally pressing, removing the second sheet; characterized in that when removing the second sheet the adhesive layer and the second porous resin layer remain adhered to the first sheet only in those areas where the ink/resin toner layer (7,8) is present. providing a first sheet, the first sheet having: a first substrate layer, a first release layer on the first substrate layer, a resin layer on the first release layer, and a first porous resin layer on the resin layer; a first substrate layer, a first release layer on the first substrate layer, a resin layer on the first release layer, and a first porous resin layer on the resin layer; providing a second sheet, the second sheet having: a second substrate layer, a second release layer on the second substrate layer, an adhesive layer on the second release layer, and a second porous resin layer on the adhesive layer; a second substrate layer, a second release layer on the second substrate layer, an adhesive layer on the second release layer, and a second porous resin layer on the adhesive layer; forming an ink/resin toner layer (7,8) in the form of a pictorial pattern by printing on the first porous resin layer of the first sheet or the second porous resin layer of the second sheet by using an electronic image forming apparatus; after forming the ink/resin toner layer (7,8), superimposing the first sheet and the second sheet with the first porous resin layer and the second porous resin layer facing each other with the ink/resin toner layer (7,8) interposed therebetween; after superimposing the first sheet and the second sheet, adhering the first sheet and the second sheet via the ink/resin toner layer (7,8) by thermally pressing the two sheets; after thermally pressing, removing the second sheet; characterized in that when removing the second sheet the adhesive layer and the second porous resin layer remain adhered to the first sheet only in those areas where the ink/resin toner layer (7,8) is present.
