    • A replaceable developer roller apparatus (10) is disclosed for a printing device (1000). The apparatus (10) includes a cylindrical developer roller (12) having two opposed ends (14, 16), and a drive assembly (22) selectively and operatively engageable with one of the opposed ends (14, 16) of the developer roller (12). The drive assembly (22) includes a shaft (24) having two opposed regions (30, 32); a gear (26) rotationally fixed to one of the opposed regions (30, 32) of the shaft (24); and a drive member (28) rotationally fixed to the other of the opposed regions (32, 30) of the shaft (24), and selectively, axially moveable between an engagement position and a disengagement position. A spindle assembly (48) is engageable with the other of the opposed ends (16, 14) of the developer roller (12). The spindle assembly (48) includes a spindle assembly shaft (50) and an alignment member (56) rotationally fixed to the spindle assembly shaft (50).
