Abstract
An image forming apparatus which permits reversible recording and erasure by a heating means, and permits storage, display, printing or reproduction of an image or other information. The present apparatus thermoreversibly records an image on a matrix material of a copolymer of styrene and butadiene and a low molecular weight, saturated carboxylic acid, preferably containing from 10 to 24 carbon atoms, and where the weight ratio of the matrix material to carboxylic acid is from 1:1 to 20:1.
Claims8
An image forming apparatus comprising:
- a means for charging a surface of a photosensitive member;
- a means for thermally writing on a thermoreversible recording medium formed on a support member;
- a means for exposing said photosensitive member when said thermoreversible recording medium is superimposed on said photosensitive member;
- a means for developing a toner image on said photosensitive member;
- a means for transferring said toner image onto a second recording medium, when said second recording medium is superimposed on said photosensitive member;
- and
- a means for fixing said toner image onto said second recording medium;
- wherein
- said thermoreversible recording medium is a mixture consisting essentially of a matrix material which consists essentially of a copolymer of styrene and butadiene, and a saturated carboxylic acid.
