PURPOSE:To obtain a surface treating method which permits free selection of the part and area of a recording object, etc. to be subjected to a surface treatment by sticking and fixing pulverous powder on the surface to be treated through a stage for developing an electrostatic image by using a developer contg. the pulverous powder having light transmittability. CONSTITUTION:An electrostatic latent image is formed on a cylindrical body 1 for holding an electrostatic latent image and is developed by the developer 5 coated by a coating means 4 for coating the insulating non-magnetic developer 5 in a hopper 3 which is a developer supplying means by regulating the thickness of the developer layer on a developer supporting means 2. At least the surface of the means 4 to be faced to the means 2 is rugged in order to coat the developer 5 on the mens 2 by regulating the thickness of the developer layer on the means 2. The rugged surface has the effect of loosening the flocculation in the developer while stirring the same and coating the developer on the means 2. Such developing device can be made the same in the form as a developing device contg. a colored developer for recording and in this case it is possible to perform surface treatment after recording by exchanging both. |
