TONER CARTRIDGE HAVING ENGAGEMENT MEMBERS

The present invention refers to a toner cartridge for use with a developer unit of an image forming device. The cartridge comprises a housing having a front, a rear, a top, a bottom and a pair of sides. The housing further has a reservoir for holding toner. An outlet port is on the front of the housing for transferring toner from the reservoir to the developer unit through an inlet port on the developer unit. A first engagement member projects from the front of the housing, the first engagement member having a first leading ramped front surface that projects further forward as it travels up the front of the toner cartridge. The first ramped front surface leads to a first vertical front surface positioned above the first ramped front surface. A second engagement member projects from the front of the housing spaced toward one of the sides of the housing from the first engagement member. The second engagement member has a second leading ramped front surface that projects further forward as it travels up the front of the toner cartridge. The second ramped front surface leads to a second vertical front surface positioned above the second ramped front surface. The second vertical front surface and at least a portion of the second ramped front surface projects further forward than the first vertical front surface.
