Hybrid developing method using specified developer and image-forming apparatus using thereof

An image-forming method, comprising:

• a process in which a toner is supported and transported on the surface of a toner supporting member placed face to face to an electrostatic latent image-supporting member, and electrostatic latent images formed on the latent image-supporting member is developed by the toner;
• and
• a process in which a two-component developer containing the toner and a carrier is supported on the surface of a developer-supporting member placed face to face to the toner supporting member and the toner is supplied onto the toner-supporting member,
• wherein the developer comprises:
• toner particles containing a binder resin and a colorant;
• a carrier that charges the toner particles in friction-contact with the toner particles;
• reverse polarity particles that are charged to polarity reversed to polarity of the toner particles charged in friction-contact with the carrier;
• and
• homopolarity particles that are charged to the same polarity as polarity of the toner particles charged in friction-contact with the carrier,
• wherein the reverse polarity particles have a peak particle size in a range from 0.1 to 0.5 μm in the particle size distribution thereof, the reverse polarity particles have a content in a range from 0.1 to 2 parts by weight relative to 100 parts by weight of the toner particles, the homopolarity particles have a peak particle size in a range from 0.005 to 0.05 μm in the particle distribution thereof, and the homopolarity particles have a content in a range from 0.1 to 2 parts by weight relative to 100 parts by weight of the toner particles.
