<P>PROBLEM TO BE SOLVED: To provide a roller and an image forming device excellent in separation working efficiency of a roller outer cover. <P>SOLUTION: The roller includes a roller shaft core 121 having a groove part 121a in a longitudinal direction, a long blade member 122 stored in the groove part 121a with an edge directed to a peripheral surface side of the roller shaft core 121, and the roller outer cover 123 covering the peripheral surface of the roller shaft core 121 storing the blade member 122 in the groove part 121a. The blade member 122 is formed by a shape-memory alloy, and the shape is memorized in advance so that at least a part of the edge is protruded from the groove part 121a and is bent or curved to the direction cutting into the roller outer cover 123 when heated at a prescribed temperature or more. <P>COPYRIGHT: (C)2011,JPO&INPIT |
