<p>PROBLEM TO BE SOLVED: To provide a toner which is hardly affected by humidity, ensures satisfactory developing performance and fixability even when allowed to stand over a long period of time and even at low humidity, enhances the transfer efficiency of a toner image from a photoreceptor and easily forms a fine pictorial full-color image free from voids due to untransfer and image defects due to the adhesion of the toner to the photoreceptor. SOLUTION: The toner has at least toner particles containing a bonding resin and a colorant and an inorganic fine powder surface-treated with a silane coupling agent of formula I, wherein R1-R3 are each OCH3 or OC2H5, (n) is an integer of 1-8 and R4 and R5 are each Cl, H, CH3 or C2H5 independently.</p> |
