ABSTRACT:
A positively chargeable single-component developer for visualizing electrostatic latent images comprises a binding resin having an acid value of 1.5 to 10 (KOH mg/g), a colorant, and an additive such as polyfluoroethylene fine powder having an electron attractive group. The additive is added in an amount of 0.05 part by weight to 2 parts by weight with respect to 100 parts by weight of the positively chargeable single-component developer. The acid value of the binding resin may be adjusted by mixing two or more resins having different acid values. The developer prevents a surface of a photosensitive member from decrease in electric potential which would be otherwise caused by electrons released when toner particles and the photosensitive member are frictionally charged. Accordingly, the developer makes it possible to provide good image quality with less fog and with a dense density.
