Abstract: PROBLEM TO BE SOLVED: To provide a non-magnetic one-component development apparatus that can form images of high quality for a long period of time without causing aggregation and liquidity degradation of toner, filming of toner to a developing roller and photoreceptor, toner-fusion to a control blade, and image defects such as ground fog, void, fading or the like. SOLUTION: In the non-magnetic one-component development apparatus 4, a developing roller 5 uses elastic materials with spring hardness of Hs (A) 45-65°, and a feed roller 7 uses foams of continuous closed-cell foam rubber materials having not less than 400/cm 2 in the number of unit cell and not more than 500 μm in the cell diameter. Further, the toner stored in a developer tank 9 uses toner particles containing binder resins and coloring agents that are externally added with inorganic fine particles of 250-600 nm in an average primary particle size.
