An image forming method is disclosed which comprises forming a latent image on a latent image bearing member, carrying a magnetic toner onto a developer carrying member provided with a magnetic field forming means, forming on the developer carrying member a layer of the magnetic toner, and developing the latent image while transferring the magnetic toner to the latent image bearing member. The magnetic toner contains a magnetic material having an intensity of magnetization of from 10 emu/g to 40 emu/g in a magnetic field of 1 K oersted and formed of a metal oxide having a horizontal direction Feret's diameter of from 0.05 mu m to 0.5 mu m, and chainlike masses of the magnetic toner, formed on the developer carrying member, are in a density of not less than 8 x 10<4> ears/cm<2> in a developing zone formed between the latent image bearing member and developer carrying member. The chainlike masses each have a length of not more than 180 mu m, and when the weight average particle diameter of the magnetic toner is r ( mu m) and the true density thereof is rho (g/cm<3>), the magnetic toner on the developer carrying member in the developing zone is in a quantity of not less than 0.06 x r x rho mg/cm<2>. Also, an image forming apparatus is disclosed. <IMAGE> |
