Abstract:
An elastic roller includes: a roller shaft; and an elastic member. The elastic roller includes an inner layer side elastic member, and a coating layer. The inner layer side elastic member includes a base layer and an intermediate layer located from the roller shaft in this order. The base and intermediate layers have a rubber hardness of 30 to 80 degrees that is measured by a durometer type A in accordance with the standard of JIS K 6253. The rubber hardness of the base layer is more than that of the intermediate layer. The coating layer is made of a silicone resin, and has a thickness of 10 to 100 μm. The silicone resin has a hardness of 20 degrees or less that is measured using a spring-based Asker C type in accordance with SRIS 0101 standard. The inner layer side elastic member has a plurality of internal grooves along a circumferential direction. Each of the internal grooves has a width of 25 to 1,300 μm, and has a depth of 25 to 500 μm. Each of the internal grooves has a V-shaped in cross section and has a groove angle of 50 to 120 degrees.
