Abstract:
A developing-agent container contains a developing agent to be supplied to a developing unit. The developing agent contains toner and carrier. The developing-agent container is filled with the developing agent with the toner and the carrier evenly distributed in a highly air-containing state. After filling the developing-agent container with the developing agent, an external force is applied on at least one of the toner and the carrier in the toner container so that a difference in forces per unit volume of the toner and the carrier due to gravity becomes small.
