To provide an elastic roll manufacturing method capable of manufacturing a high performance elastic roll, which develops high performance when incorporated in a thermal fixing apparatus or the like, at a low cost, and also to provide the high performance elastic roll and the high performance thermal fixing apparatus capable of fixing toner with high image quality.
The elastic roll manufacturing method for manufacturing the elastic roll wherein an elastic layer and a fluoroplastic layer are provided on the surface of a core body in this order is composed of an elastomer forming process (step S20) for forming an elastic material into a tubular shape having an inner hole, of which the peripheral length is below 85% of the outer periphery of the core body 210, separately from the core body 210 to form a tubular elastomer 220 and an air removing process (step S50) for placing the roll body obtained in an insertion process (step S40) under a reduced pressure environment to remove the air involved in the gap between the tubular elastomer 220 and the core body 210.
