PROBLEM TO BE SOLVED: To provide a development apparatus capable of binary development, low developing potential and obtaining proper images. SOLUTION: In the development apparatus provided with a development roller for holding toner on a surface and carrying the toner to a development area opposite to a latent image-holding element, and a toner supplying roller for holding a two-component developer, including the toner and a carrier, carrying the two-component developer to a toner-supplying area opposite to the development roller and supplying only toner from the two-component developer to the development roller, there is no member for abutting against an image area on the development roller 16, except for the latent image holding element (a photoconductor drum 17) and a two-component developer G. Since stresses on the toner are reduced, the toner is prevented from being fixed on the development roller, filming and being scratched, etc. |
