Sheet processing method and image forming apparatus

摘要

A sheet processing method including superimposing a transparent sheet having a mirror image thereon on a non-transparent sheet so that a surface of the transparent sheet having the mirror image faces the non-transparent sheet with an adhesive medium therebetween. An image forming apparatus includes an image forming means for forming a mirror image on a transparent sheet, and a heating and pressing means for applying heat and pressure to the transparent sheet and a non-transparent sheet on which the transparent sheet is superimposed so that a surface of the transparent sheet having the mirror image faces the non-transparent sheet. The non-transparent sheet includes a heat-sensitive adhesive layer including an adhesive medium including a thermoplastic resin and a solid plasticizer, on a surface facing the surface of the transparent sheet having the mirror image.
