Abstract
Coating of heat-soluble material on a substrate or cleaning is performed by supplying a heat-soluble material in heated and melted condition onto a substrate, laying a sheet member on the heat-soluble material, cooling the heat-soluble material to solidify, and peeling off the sheet member.
Claims9
A cleaning method for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising the steps of:
- supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed;
- laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying substrate;
- cooling said heat-soluble material to solidify said heat-soluble material;
- and
- separating said image-carrying substrate and said cleaning sheet member from each other such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
A cleaning apparatus for removing an image-forming material formed on a surface of an image-carrying substrate from said surface of said image-carrying substrate, comprising:
- means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying substrate on which said image-forming material has been formed;
- means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying substrate;
- and
- means for separating said image-carrying substrate and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying substrate to said cleaning sheet member together with the solidified heat-soluble material.
A printing apparatus comprising:
- erasing means for erasing an image-forming material formed on a surface of an image-carrying sheet to obtain an erased image-carrying sheet;
- and
- means for forming a new image-forming material on said surface of said erased image-carrying sheet according to an image data,
- wherein said erasing means comprises:
- means for supplying a heat-soluble material in heated and melted condition onto said surface of said image-carrying sheet on which said image-forming material has been formed;
- means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface of said image-carrying sheet;
- and
- means for separating said image carrying sheet and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying sheet to said cleaning sheet member together with the solidified heat-soluble material.
A printing apparatus comprising:
- means for forming an image-forming material on a surface of an image-carrying member according to an image data;
- means for transferring said image-forming material formed on said surface of said image-carrying member to a member to be printed;
- and
- cleaning means for removing said image-forming material remained untransferred on said surface of said image-carrying member, said cleaning means comprising:
- means for supplying a heat-soluble material in a heated and melted condition onto said surface of said image-carrying member;
- means for laying a cleaning sheet member on said heat-soluble material supplied onto said surface and said image-carrying member;
- and
- means for separating said image-carrying member and said cleaning sheet member from each other, after said heat-soluble material has cooled and solidified, such that said image-forming material is moved from said surface of said image-carrying member to said cleaning sheet member together with the solidified heat-soluble material.
