Title: Method and device for recording
Inventor: KATANO YASUO
IPC: B41J2/325
Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To improve a transferring property and to enhance reliability in high speed recording and color recording by a method wherein a latent image is formed on a special recording medium and is developed, then the recording medium is supported by an elastic body at a portion where a coloring material forming an image is transferred to a recording paper and a transferring pressure having a specific value is applied thereto at the transferring portion. SOLUTION: A recording body 1, which is formed such that a recording layer having a characteristic that a retraction contact angle against a liquid is lowered when it is heated and cooled by being in contact with the liquid, is provided to a base body. Printing is performed by surely holding the recording body 1 on an elastic holding member 6. In the case where the recording body is detachably attached to the elastic holding member 6, it is possible to exchange the recording body when it is deteriorated so that the reliability is enhanced. When the recording body 1 is deformed along the irregularities of a paper 20 at a transferring section, it is good to raise a transferring pressure, but when it is too high the rubbing resistance of the recording body is possibly deteriorated.  The transferring pressure is preferably set to one MPa or more when considering that at least 1.0 is required for an image density.
