Image forming apparatus having first and second retractable toner cartridges

An image forming apparatus comprising:

• a rotary configured to rotate and 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 with an opening, the body frame being configured to accommodate the rotary;
• 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 support member which is configured to support the first toner cartridge, to which the first toner cartridge is detachably attached, and which is attached to the rotary;
• and
• a second support member which is configured to support the second toner cartridge, to which the second toner cartridge is detachably attached, and which is attached to the rotary,
• wherein the first support member is movable with respect to the first storage frame such that the first toner cartridge moves from the first attached position to the first retracted position,
• wherein the second support member is movable with respect to the second storage frame such that the second toner cartridge moves from the second attached position to the second retracted position,
• wherein in a case where a length by which the first toner cartridge at the first retracted position projects from the opening is a first length, and a length by which the second toner cartridge at the second retracted position projects from the opening is a second length, the first length is larger than the second length, and
• wherein a movement distance of the first support member in a case where the first toner cartridge moves from the first attached position to the first retracted position is larger than a movement distance of the second support member in a case where the second toner cartridge moves from the second attached position to the second retracted position.
