摘要： An image forming apparatus of the present invention includes a developing unit for developing a latent image formed on an image carrier with a two-ingredient type developer, i.e., a toner and carrier mixture. A toner replenishing device replenishes toner stored in a toner storing portion to the developing unit. A carrier storing portion, storing a carrier therein, is constructed independently of the toner storing portion. The carrier is fed from the carrier storing portion to the developing unit by a toner conveying force available with the toner replenishing device.

摘要： A toner container includes a storing body that stores toner, a toner reception opening that receives the toner from the toner storing body, a shutter opening, a cylindrical shutter, and an O-shaped elastic ring disposed at the shutter opening configured to seal a space between the shutter opening and the shutter. The shutter receives a nozzle of an image forming apparatus and the cylindrical shutter opens and closes the shutter opening when moved by a nozzle of the image forming apparatus inserted into the shutter opening. When the nozzle is disposed through the shutter opening, the toner which is received from the toner reception opening is subsequently received by the nozzle of the image forming apparatus.
