摘要： The present invention provides new image forming methods. The image forming methods use a combination of a light-sensitive material and an image receiving material. The light-sensitive material comprises a support, a strippable layer and a light-sensitive polymerizable layer in order. The light-sensitive polymerizable layer contains silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound or a cross-linkable polymer. The light-sensitive polymerizable layer may further contain a colorant. An image forming method using the light-sensitive polymerizable layer containing no colorant comprises an exposing step, a developing step, a toning step and a transferring step. Another image forming method using the colorant-containing light-sensitive polymerizable layer comprises an exposing step, a developing step, a removing step and a transferring step. The present invention is characterized in that an image formed on the strippable layer is entirely transferred to the image receiving material. The strippable layer has a thickness of not less than 1.0 .mu.m. A new light-sensitive material having the strippable layer is also disclosed.
