Title:
DRIVING DEVICE FOR ROTARY IMAGE FORMING BODY
Document Type and Number:
Japanese Patent JP3268479
Kind Code:
B2
Abstract:
PURPOSE: To smoothly rotate a rotary image forming body at stable speed with stable driving torque by making the rigidity of a rotary body driving system small.
CONSTITUTION: A pair of projected parts 10A is formed on the end face of a photoreceptor drum 10, and a leaf spring member 10B whose leading edge is bent in U-shape is attached to the projected part 10A. Meanwhile, a pressing pin 30P corresponding to the member 10B is protrusively provided on the side surface of a driving gear 30. By driving the driving gear 30, the pin 30P presses the member 10B, and the drum 10 is rotated by the reaction of the elastic deformation.
