Summary:A single component development device including a toner including a resin, a coloring agent, a wax, a charge control agent and an inorganic particulate, a development roller to bear the toner on the surface of the development roller and transfer the toner to an image bearing member and a thin layer forming member to regulate the thickness of the layer of the toner while in contact with the surface of the development roller via the toner borne thereon, wherein the regulating pressure A between the thin layer forming member and the development roller is from 25 to 60 (N/m), the content Z (weight %) of the charge control agent satisfies the following relationship (1) and the average dispersion particle diameter D (nm) of the charge control agent satisfies the following relationship (2): 0.029 × A - 0.150 > Z > 0.013 × A - 0.013 D < 6.3 × A - 106.3
