PROCESSING BOX

摘要

A processing box comprises a toner hopper, a development bin and a waste hopper. Two end covers are disposed opposite to each other. The end covers are disposed at two ends of the toner hopper, development bin and waste hopper, and connect the toner hopper, development bin and waste hopper. A resilient cushioning and connecting member is disposed between the toner hopper and the development bin. The resilient cushioning and connecting member comprises a first frame member, a second frame member and a sponge frame member. The first frame member is fixedly mounted on an end, near the development bin, of the toner hopper, and has a toner outlet. The second frame member is fixedly mounted on an end surface, corresponding to the toner outlet, of the development bin. The sponge frame member is bonded between the first frame member and the second frame member. A sponge connecting member structure is disposed between the toner hopper and the development bin. By taking advantage of the tightness, flexibility, and resilience of the sponge, the tightness of a connecting portion between the toner hopper and the development bin is ensured, a relative expansion amount is maintained between the development bin and the toner hopper, and recovery of the toner hopper becomes more convenient without affecting the printing quality.
