Abstract
A developer for developing an electrostatic latent image is disclosed. It is obtained by mixing a chargeable magnetic toner mainly composed of a binder resin and magnetic powder, which toner has a volume resistivity of 10.sup.13 .OMEGA..multidot.cm or greater, with a magnetic carrier having a volume resistivity of 10 .OMEGA..multidot.cm or greater and less than 10.sup.6 .OMEGA..multidot.cm at a weight ratio of between 10:90-90:10. A method of forming an image is also disclosed. An electrostatic latent image is formed on an image carrier. A magnetic brush formed of the developer slides against the surface of the image carrier. The visualized toner image is transferred to a recording medium. The previously-applied toner remaining on the surface of the image carrier is removed after transferring is completed and an electrostatic latent image is visualized when the magnetic brush slides against the surface of the image carrier.
