Abstract: A toner cartridge includes a container main body includes a toner outlet, a shutter mechanism for opening and closing the toner outlet, a lever for operating the shutter mechanism, a lever locking mechanism, a lock releasing mechanism, and a prevention mechanism. The lever locking mechanism locks the lever so as to be inoperative while the toner outlet is closed. The lock releasing mechanism unlocks the lever locked by the lever locking mechanism in conjunction with installment of the container main body into the image forming device. The prevention mechanism prevents the container main body from being taken out of the image forming device while the container main body is installed in the image forming device, and the lever operates to open the toner outlet.

Abstract: A color printer includes a color printer main body, a photosensitive drum, a rotary development device, a plurality of toner containers and a drive power transmission mechanism. The drive power transmission mechanism includes a housing, a shaft member, a first transmission mechanism, and a second transmission mechanism. The housing is mounted on the color printer main body. The shaft member is mounted in the housing so as to be axially rotatable, and mobile in the axial direction. The first transmission mechanism is mounted in the housing and transmits the drive power of the drive motor to the shaft member, so that the shaft member can be moved in the axial direction. The second transmission mechanism is mounted in the housing and transmits the drive power of the drive motor to the shaft member, so that the shaft member can be rotated.

Abstract: Toner containers are disclosed which are arranged in a horizontal direction, each toner container including (a) a container body that has an opening formed in the top thereof, and a first brim member formed around the entire circumference of the opening so as to protrude outward, and (b) a container lid that has an opening formed in the bottom thereof, and a second brim member formed around the entire circumference of the opening so as to protrude outward and connected to the first brim member. Here, the left side brim member and the right side brim member of the first brim member and the second brim member are formed in different positions in the vertical direction.
