Claims

[Scope of utility model registration request]

It has a flexible transfer material support member for supporting the transfer material and a transfer material carrier that moves endlessly while supporting the transfer material, and the transfer material support member and the transfer material carrier move in the moving direction. In a transfer device including a cleaning member, at least one end of the engaging portion is elastically engaged in the circumferential direction via an elastic body, and the cleaning member contacts and cleans the transfer material support member, at least the cleaning member of the transfer material support member. A transfer device characterized in that a circumferential end of the contact portion is provided with an overhanging portion that also overlaps with respect to expansion and contraction from one end side to the other end side with respect to the moving direction.
