An electrophotographic image forming device includes a replaceable unit having a body with a toner reservoir. A drive element on a rear end of the body is unobstructed to mesh with a corresponding drive element in the image forming device. A toner outlet port is positioned on a bottom of the body near the rear end of the body. A latch catch is positioned on a first side of the body to receive a corresponding latch when the replaceable unit is installed in the image forming device. A latch actuator at the front end of the body is movable between a home position and a releasing position. A release handle at the front end of the body is operatively connected to the latch actuator such that actuation of the release handle causes the latch actuator to move from the home position to the releasing position to unlatch the body.

A cartridge includes: a housing; a storage medium including an electrical contact surface; and a storage medium holder holding the storage medium and movable relative to the housing. The storage medium holder is positioned at one end portion of the housing in a first direction and includes: a first holder holding the electrical contact surface; a second holder positioned spaced away from the first holder in a second direction crossing the first direction; and an elastic member expandable and shrinkable in the second direction between the first holder and the second holder. The first holder has a first hole penetrating the first holder in the second direction. The first hole is positioned farther from the housing in the first direction than the second holder and the elastic member are from the housing in the first direction and is overlapped with the electrical contact surface as viewed in the second direction.
