Patent ID: 8841054

Claim:
An image-forming method comprising applying an alternating field between a latent image bearing member and a toner bearing member bearing a magnetic toner on the surface thereof and having inside a unit for generating a magnetic field, the latent image bearing member and the toner bearing member being placed with a predetermined interval therebetween, to develop an electrostatic latent image formed on the latent image bearing member with the magnetic toner, wherein the toner bearing member has an outer diameter of 6.0 mm or more and 10.0 mm or less, the magnetic toner includes magnetic toner particles containing at least a binder resin and a magnetic powder, an inorganic fine powder as a flowability-improving agent, and fine particles having a primary particle diameter in excess of 30 nm, the magnetic toner has an average circularity of 0.950 or more and a compressibility of 30 or less obtained from the following expression (1): Compressibility={1−(apparent density/tap density)}×100 (1); and a total energy of the toner measured with a powder flowability measuring apparatus satisfies the following expressions (2) and (3): 600≦TE 10 ≦1,500 (2) TE 10 /TE 100 ≦1.60 (3) where TE 10 represents total energy (mJ) when a stirring rate is stirred is 10 mm/sec, and TE 100 represents total energy (mJ) when a stirring rate is stirred is 100 mm/sec.
