Abstract
A web transfer belt is provided having a good paper releasability with good paper releasability and having stable surface features. The web transfer belt includes a high-molecular weight elastic member 2 having a web-receiving face 2b for receiving a web P to transfer, and a surface layer forming member 3 disposed on the high-molecular weight elastic weight member 2. A portion of high-molecular weight elastic weight member 2 is exposed on web-receiving face 2b, with one of the web-receiving face 2b and surface layer forming member 3 being made of a hydrophobic material. In this way, water-repellent portions and water-condensing portions are dispersed on the web-receiving face, with recesses and protrusions at fine scales, which can break a water film formed between web-receiving face 2b and web P, and can be easily formed on the web-receiving face 2b.
