1. A first replaceable unit for use with a second replaceable unit in an electrophotographic image forming device, comprising:
a housing having a reservoir for holding toner; and
a latch movable relative to the housing between a latching position for latching the first replaceable unit to the second replaceable unit and an unlatching position for permitting the first replaceable unit to separate from the second replaceable unit, the latch includes a latching contact surface for contacting a corresponding latch catch on the second replaceable unit in order to prevent the first replaceable unit from separating from the second replaceable unit when the first replaceable unit is mated with the second replaceable unit and the latch is in the latching position, the latch includes a first cam follower surface for contacting a corresponding first camming surface on the second replaceable unit during mating of the first replaceable unit with the second replaceable unit to cause the latch to move toward the unlatching position to clear the corresponding latch catch during mating of the first replaceable unit with the second replaceable unit, the latch includes a second cam follower surface for contacting a corresponding second camming surface on the second replaceable unit during mating of the first replaceable unit with the second replaceable unit to cause the latch to move toward the latching position to position the latch in the latching position when the first replaceable unit is fully mated with the second replaceable unit.
