The heat-resistant resin layer is formed by injecting a polyamide acid solution in a rotational drum, and then formed by centrifugal forming by rotating the rotational drum on rollers under heating. After forming, imidization is conducted by heating and baking to form a film member of a thermosetting polyimide.Type: GrantFiled: May 30, 2001Date of Patent: April 13, 2004Assignee: Fuji Xerox Co., Ltd.Inventors: Ryuichiro Maeyama, Yasuhiro Uehara, Michiaki Yasuno, Makoto Omata
