    • PROBLEM TO BE SOLVED: To provide an image removal method for an image forming substance on a recorded material, and an image removal device that is excellent in maintenance and can be used for a long time. SOLUTION: The image forming substance removal method includes: the step in which a thermoplastic image forming substance formed on a recorded material is heated to a temperature at which the substance exhibits plasticity; the step in which the image recorded surface of the recorded material and each peeling member are brought into contact with each other and superposed and pressure is applied to the recorded material while the image forming substance on the recorded material exhibits plasticity; and the step in which the recorded material and peeling member superposed one on the other are separated such that the image forming substance on the recorded material is transferred to the peeling member and thus removed. In the image forming substance removal method, the steps of superposition, the application of pressure and separation are repeated a plurality of number of times. The peeling member whose surface layer comes into contact with a recorded material does not exhibit plasticity at temperatures under pressure is used for the steps of superposition, the application of pressure and separation conducted for the upstream side. The peeling member whose surface layer comes into contact with a recorded material exhibits plasticity at temperatures under pressure is used for the steps of superposition, the application of pressure and separation conducted for the downstream side.

    • 要解决的问题:为了在记录材料上提供图像形成物质的图像去除方法,以及保持良好并且可以长时间使用的图像去除装置。 图像形成物质的除去方法包括:将形成在记录材料上的热塑性成像物质加热到物质呈现塑性的温度的步骤; 将记录材料的图像记录表面和每个剥离部件彼此接触并将重叠的压力施加到记录材料上,同时记录材料上的成像物质表现出可塑性的步骤; 并且将记录材料和剥离构件重叠在一起的步骤被分离,使得记录材料上的图像形成物质被转移到剥离构件并因此被去除。 在成像物质去除方法中,叠加,压力和分离的步骤重复多次。 表面层与记录材料接触的剥离部件在压力温度下不呈现塑性,用于叠加,施加压力和对上游侧进行分离的步骤。 其表面层与记录材料接触的剥离部件在加压温度下显示出可塑性,用于叠加,施加压力和向下游侧进行分离的步骤。 版权所有(C)2006,JPO&NCIPI
