PURPOSE:To enable high-speed copying only by applying electric energy, by providing a magnetic roll for attracting and recovering UV shading particles attached to a transferred image, and a guide plate for leading said particles recovered on this roll into the bottom of a cylinder. CONSTITUTION:The present diazo copying arraratus comprises magnetic UV ray shading particles 14 attached to a transferred pattern by Coulomb's force, a developing station for visualizing a latent image on a diazo photosensitive paper 21 closely attached to the outer surface of a dielectric cylinder through the pattern of the particles 14 attached to the pattern in the cylinder 9, a destaticizer 8 for removing the charge of the latent image pattern after the transfer, and a magnet roll 16 for attracting and recovering the particles 14 attached to the transferred image. In addition, a guide plate 19 having vapor-deposited metal low in contact resistance and good in electric conductivity on the surface is also provided and it guides the particles 14 recovered on the magnet 16 into the bottom of the cylinder 9. |
