Claims

[Scope of utility model registration request]

In a toner replenishing device that replenishes toner by attaching a toner replenishing container to a toner replenishing part of a developing device, the toner replenishing container includes first and second bottom walls each having an opening that does not coincide with each other. , the second bottom wall is curved inwardly and positioned above the second bottom wall, the second bottom wall being made of a resilient material and extending from the outer surface of the first bottom wall. The shape can be changed into two shapes: a curved shape along the curve, and a shape curved outward away from the first bottom wall, and the curved side part extends outward from the first bottom wall. The developer replenishing portion includes a first retaining member that interferes with the protruding portion of the second bottom wall of the toner replenishing container to be mounted and bends the second bottom wall outward; a second engaging member that interferes with the protruding portion of the second bottom wall of the toner replenishing container and bends the second bottom wall inward. .
