ABSTRACT:
This invention relates to a developing method which comprises forming a developing agent layer on the surface of a developing agent-carrying body by pressing a developing agent to the developing-agent carrying body by means of a coating member, and electrostatically depositing toner particles from the developing agent layer onto an electrostatic latent image formed on an image-bearing body which faces the developing agent layer. The developing agent contains toner particles including a synthetic resin with a glass transition point of 50.degree. C. or above and a softening point of 110.degree. to 116.degree. C. and white or colorless auxiliary particles, said auxiliary particles being capable of being oppositely charged with respect to the polarity of the charge on the charged toner particles or charged to a lower positive potential than the positively charged toner particles or charged to a higher negative potential than the negatively charged toner particles.
