Helically splined drive member for an image forming device

摘要

Embodiments for driving a removable element within an image forming device. An output member positioned within the image forming device mates with an input member of the removable element. The members include ribs that mate together such that rotational force from the output member is transferred to the input member. The ribs of the members include non-complementary contact surfaces that provide for limited contact along the contact surfaces that accurately transfers the driving force.
