<p><P>PROBLEM TO BE SOLVED: To prevent occurrence of toner aggregates by selecting a toner excellent in antiblocking property when a toner conveyance path is set in a high-temperature place, thereby a conveyance amount of a developer is stabilized. <P>SOLUTION: Five or more developing devices each for developing an electrostatic latent image formed on a latent image carrier with a developer to form a visible image are arranged. At least four of the five or more developing devices house toners for forming yellow, magenta, cyan and black images, respectively, and a toner excellent in anti-blocking characteristic is selected for a developer passing through a replenishment path close to a fuser among developer replenishment paths through which developers to be replenished to the respective developing devices pass. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
