ABSTRACT:
A drive connection mechanism has a sliding unit which is fixed to a drive shaft extending through the photoconductive drum, a convex coupling gear which has three coupling members fixed slidably to splines formed in the periphery of the sliding unit, a compressing spring which energizes the coupling gar, and a concave coupling gear which is provided in the drum to receive and fit the convex coupling gear. When the convex coupling gear is pressed to the concave coupling gear, a force from the tapered surface to the inside acts on each coupling member. Then, the bevel gear of the convex coupling gear is stuck to the bevel gear of the concave coupling gear, the internal gears of the convex coupling gear is stuck to the splines of the drive shaft, and the centers of the drive shaft and photoconductive drum are aligned.
