Abstract:
In a case where a transfer roller is viewed from a direction orthogonal to a rotation axis direction of a shaft, the shaft includes in a longitudinal direction a first contact portion which is provided on an end portion side of an elastic portion and in which the shaft and the elastic portion are in contact with each other and a second contact portion which is provided on a more inner side than the first contact portion and in which the shaft and the elastic portion are in contact with each other. The transfer roller includes a void between the first contact portion and the second contact portion in the longitudinal direction, and the void is arranged at least on a more inner side than an end portion of a transfer material having a maximum size.
