Image forming apparatus having detachable toner cartridges

An image forming apparatus comprising:

• a rotary including a first developing roller, a second developing roller, a first storage frame, and a second storage frame, the first storage frame including a first storage portion configured to store first toner to be supplied to the first developing roller, the second storage frame including a second storage portion configured to store second toner to be supplied to the second developing roller;
• a body frame configured to accommodate the rotary and having an opening;
• a first toner cartridge which is configured to store the first toner, which is attachable to and detachable from the rotary through the opening, which is movable to a first attached position and a first retracted position where the first toner cartridge is retracted from the first attached position, with respect to the first storage frame, and which is configured to supply the first toner to the first storage portion in a state in which the first toner cartridge is at the first attached position;
• a second toner cartridge which is configured to store the second toner, which is attachable to and detachable from the rotary through the opening, which is movable to a second attached position and a second retracted position where the second toner cartridge is retracted from the second attached position, with respect to the second storage frame, and which is configured to supply the second toner to the second storage portion in a state in which the second toner cartridge is at the second attached position;
• a first moving device configured to move the first toner cartridge from the first attached position to the first retracted position;
• and
• a second moving device configured to move the second toner cartridge from the second attached position to the second retracted position;
• and
• an opening/closing member provided to be, with respect to the body frame, movable between a closed position where the opening/closing member covers the opening and an open position where the opening/closing member opens the opening to allow attachment and detachment of the first toner cartridge and the second toner cartridge to and from the rotary through the opening,
• wherein the opening/closing member is configured to move from the closed position to the open position in an interconnected manner with movement of the first toner cartridge from the first attached position to the first retracted position by the first moving device, and
• wherein the opening/closing member is configured to move from the closed position to the open position in an interconnected manner with movement of the second toner cartridge from the second attached position to the second retracted position by the second moving device.
