PURPOSE:To eliminate fluctuation in the positive electrostatic charge quantity among toner particles by incorporating metal complex of a specific Schiff base as an electric charge control agent into the titled compsn. CONSTITUTION:The metal complex of the Schiff base expressed by the formula is added as the charge control agent into the developer compsn. In the formula, R1, R2 denote H, (un)substd.alkyl, halogen. For example, Cr complex of ethylene bis(salicylimine), etc., are usable for said complex. This complex may be added to any part of the compsn. if said complex can exhibit the positive electrostatic chargeability thereof. The complex is used by being dispersed in a resin binder or being stuck to the surface of the toner particles in the case of using the complex for a one-component developer or two-component developer. |
