Toner container having a toner port shutter interface

A toner container for use with a developer unit of an image forming device, comprising:

• a body having a top, a bottom, a first side and a second side positioned between a first longitudinal end and a second longitudinal end of the body, the first longitudinal end of the body leads during insertion of the toner container into the image forming device and the second longitudinal end of the body trails during insertion of the toner container into the image forming device, the body has a reservoir for holding toner;
• an outlet port on the bottom of the body and adjacent to the first longitudinal end of the body for exiting toner from the toner container;
• a toner container shutter that is movable between a closed position blocking the outlet port and an open position unblocking the outlet port;
• an engagement member projecting downward from a bottom surface of the toner container shutter, a front face of the engagement member that faces toward the first longitudinal end of the body is unobstructed to contact and push open a developer shutter of an inlet port of the developer unit in a direction from the second longitudinal end of the body toward the first longitudinal end of the body during insertion of the toner container into the image forming device;
• and
• an extension protruding from the toner container shutter in a direction from the second longitudinal end of the body toward the first longitudinal end of the body and unobstructed at the first longitudinal end of the body for contacting a corresponding surface in the image forming device during insertion of the toner container into the image forming device and receiving an actuation force from the corresponding surface in the image forming device to move the toner container shutter relative to the body in a direction from the first longitudinal end of the body toward the second longitudinal end of the body from the closed position to the open position during insertion of the toner container into the image forming device.
