Claims (1)

[Claims for Utility Model Registration] (1) Between a transfer section that transfers the toner image on the photoreceptor to a transfer material and a transfer roller that supplies the transfer material to the transfer section, the transfer material that has passed through the transfer roller. A copying machine characterized in that a plurality of buffering members are provided in a direction transverse to a direction in which a transfer material travels to reduce the impact of bouncing motion of a rear end portion. (2) The copying machine according to claim 1, wherein each of the members is always located at a position to reduce the impact of bouncing motion of the rear end of the transfer material. (3) Each of the members is supported so as to be able to reciprocate between a position for mitigating the impact of the bouncing action of the rear end of the transfer member and a position retreated from the position, and the transfer material is The transfer material is placed in the retracted position before entering between the transfer section and the conveyance roller, and after the transfer material enters between the transfer section and the conveyance roller,
2. The copying machine according to claim 1, wherein the copying machine is arranged at a position to reduce the impact before the rear end of the transfer material completes passing through the roller.
