The second roller is disposed parallel to the first roller. The endless rotary belt is looped for rotation around the first and second rollers. The third roller is disposed opposite the first roller via the belt. The heater is positioned adjacent to the belt to heat the belt. The first and third rollers press against each other via the belt to form a nip therebetween. The belt cooler is disposed inside the loop of the belt downstream from the first roller and upstream from the second roller for cooling the belt. The belt cooler has a convex contact surface. The upstream guide member is disposed inside the loop of the belt upstream from the contact surface to guide the belt.

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.

摘要： A developer container storing a developer of the present invention includes a developer outlet formed in the side wall thereof, and a shutter member for selectively opening or closing the developer outlet. The shutter member opens the developer outlet when the developer container is mounted to the body of an image forming apparatus or closes it when the former is dismounted from the latter. The toner container with this configuration surely prevents the developer from leaking when the developer container is dismounted from an image forming apparatus.
