Claim:
An image-forming apparatus, comprising: an endless conveyor belt rotatable to convey paper with a surface of the conveyor belt being charged; a counter roller for holding the paper between the conveyor belt and the counter roller and conveying the paper; and a clutch part that is caused to slip by a difference in velocity between the conveyor belt and the counter roller, wherein a linear velocity of the counter roller is set to be lower than a linear velocity of the conveyor belt, the paper is conveyed at a velocity of the conveyor belt and the counter roller is caused to slip by the difference in velocity between the conveyor belt and the counter roller, when the paper does not slip relative to the conveyor belt, and said counter roller is caused to operate together with said clutch part so that the paper is conveyed at a velocity of the counter roller, when the paper slips relative to the conveyor belt.
