Abstract:
An image-forming apparatus comprising:an image-bearing body having a surface on which a toner image is formed;transfer means for transferring the toner image formed on the image-bearing body onto a copying material by allowing the copying material to contact the image-bearing body the width of the contact being represented by L and the surface velocity or the image-bearing body being Vp, the transfer means being constituted by a dielectric layer that is stacked on a conductive base, the transfer means having a time constant .tau. equal to a product of the resistance and the capacitance between the image-bearing body and the transfer means so that the relationship represented by L/Vp<.tau. is satisfied; andattracting means for electrically attracting and holding the copying material onto the transfer means prior to transferring the toner image onto a copying material, the attracting means being placed on the periphery of the transfer means.
