ABSTRACT:
A copying machine of the present invention is constructed such that, when a toner in a toner containing portion provided in a developing unit is emptied, a toner supply container whose opening for supplying toner is sealed is mounted in the toner containing portion. An opening member for unsealing the opening for supplying the toner of the toner supply container is included in the toner containing portion, so that the toner can be replenished without staining the surroundings, and since the toner can be replenished only at frequencies restricted in advance, deterioration of copying quality can be avoided.
