Abstract
An image-forming device includes a photosensitive drum, a transfer roller, a guide plate for guiding the paper toward the photosensitive drum, and a sponge fixed to the bottom surface of the guide plate. The sponge is softer than the guide plate, so that it can absorb vibrations in the guide plate when the trailing edge of the paper leaves the guide plate.
