Abstract
An image forming method, including the steps of: forming a toner image with a toner having toner particles and an external additive on a surface of a first image-carrying member which includes a support and a lamination layer disposed thereon containing a peeling layer, fixing the toner image on the surface of the peeling layer of the first image-carrying member to form a fixed image, peeling the peeling layer having the fixed image from the first image-carrying member, and transferring the fixed image on the peeling layer onto a second image-carrying member while swelling the peeling layer, wherein the lamination layer has at least the peeling layer and an adhesive layer, the peeling layer at least including a transfer layer and having an area expansion ratio of 102-106%. The transfer layer may preferably be a composition containing a high-saponified polyvinyl alcohol having a saponification degree of at least 90% and a low-saponified polyvinyl alcohol having a saponification degree of below 90%. The binder resin may preferably be polyester resin having an acid value of 2-25 mg KOH/g. The peeling layer having an appropriate area expansion ratio (102-106%, preferably 102-105%) is effective in allowing quick and uniform peeling thereof from the fixed image.
