Abstract:
An image forming device comprising:a driving unit including a first coupling member having a groove or a projection for transmitting a rotating force, said driving unit being made of a conductive material, electrically grounded, and rotatable; and a photoreceptor assembly as a driven section rotated by said driving unit, said photoreceptor assembly including a photoreceptor and a second coupling member, and being attachable to/detachable from said driving unit, said second coupling member having a projection or a groove for engaging with said groove or said projection of said first coupling member, rotation of said driving unit being transmitted to said photoreceptor by the engagement of said first coupling member and said second coupling member, and when said photoreceptor is being rotated by said driving unit, said projection or said groove of said second coupling member and said groove or said projection of said first coupling member being electrically connected by a pressured contact with each other, thereby grounding said photoreceptor, wherein an electrical resistance value between said first coupling member and said second coupling member at the time said photoreceptor assembly is being rotated by said driving unit is 1,000 &OHgr; or less.
