Abstract

PURPOSE: To enhance the quality of transfer images by performing prewetting to a transfer sheet by the prewetting roller formed by material of ≤20 dyne/cm surface energy.
CONSTITUTION: A prewetting roller 19 consists of a roller having a covering 22 on a core metal 21 fixed to or integrally formed with a fixing shaft 20. The covering 22 is formed by material of ≤20 dyne/cm in surface energy and may be directly put on the core metal 21 or be done so by way of an elastic material 23. Polymer of tetrafluoro- or hexafluoroolefin is suitable as the covering material, and polyurethane rubber and chloroprene rubber are convenient for the elastic material. The use of the material of small surface energy for the covering of the prewetting roller enables the enhancement of the quality of transfer images by the effect of assuring moderate prewetting and preventing toner transfer.
