DRIVE TRANSMITTER AND IMAGE FORMING APPARATUS INCORPORATING THE DRIVE TRANSMITTER

摘要

A drive transmitter (50) that is applicable to an image forming apparatus includes a first coupler (161), a second coupler (162), and reinforcing ribs (161e). The first coupler (161) is mounted on an axial end of a first rotary shaft (63) and is provided with extensions (161c). The extensions (161c) extend in an axial direction of the first coupler (161) and are arranged at intervals in a rotation direction thereof. The second coupler (162) is mounted on an axial end of a second rotary shaft (431b) and is provided with contact parts (162h) to which the respective extensions (161c) contact between the first rotary shaft (63) and the second rotary shaft (431b) upon drive transmission. The reinforcing ribs (161e) are provided to the respective extensions (161c) and reinforce the respective extensions (161c).
