PURPOSE:To always obtain a high-contrast image with no fog, by mixing a specific material of an organic silicone polymer, etc. and a metallic complex into the surface of a member that applies the friction electric charge to an insulating toner and then developing an electric latent image. CONSTITUTION:An electric latent image is developed by using an insulating toner received the friction electric charge not using the carrier particles. In such case, one or more types of materials selected from the group consist of inorganic silicone polymer, aliphatic compound containing fluorine, styrene resin and polyphenylene oxide and a metallic complex having 2-6 coordination number are mixed into the surface of a member that apolies the friction electric charge to the above-mentioned toner. for the organic silicone polymer, the silicone varnish that contains the RSiO3/2 unit (R: alkyl, phenyl, vinyl) with a 3-dimensional structure is desirable. The metal is ideal to be the 1st transition metal for the metallic complex, and a salcylic acid derivative is preferably used for the ligand respectively. |
