Formation of a plurality of wear visibility grooves 10 has been focused. An elastic roller includes: an inner layer side elastic material 4; a coating layer 5 disposed on an outer periphery of the inner layer side elastic material 4, the coating layer configured to make contact with the belt-shaped member; and a plurality of wear visibility grooves 10 (11, 12, 13) formed on an inner side of the coating layer 5 and formed on a surface of the inner layer side elastic material 4 in a circumferential direction, the plurality of wear visibility grooves being successively formed in an axial direction of the roller shaft, wherein at least two grooves of the plurality of wear visibility grooves have different heights, and filler is filled in the plurality of wear visibility grooves 10, the filler having a color different from that of the inner layer side elastic material 4 and different from that of the coating layer 5, and material of the filler is the same as that of the coating layer 5.
