A fixing belt for use in an image forming apparatus such as an electrophotographic copying machine and a printer, the fixing belt having excellent durability, heat resistance, toner release property, and smoothness capable of coping with fine toner. provide. A fixing belt having a single layer is dehydrated by heating a polysiloxane component having a structural unit represented by the formula (1) and a polyamic acid component represented by the formula (2), or the polyamic acid. It is manufactured using a polyimide silicone resin obtained from a polyimide silicone resin precursor composition containing a polyimide resin component obtained by ring closure. [In the formula, R is a monovalent organic group having 10 or less carbon atoms, R1 is a hydrogen atom or a monovalent organic group having 10 or less carbon atoms, and m is an integer of 3 or more. X is a tetravalent organic group, Y is a divalent organic group, and n is an integer of 1 or more. [Selection diagram] None |
