Abstract
Provided is a method for image formation capable of stably outputting high-quality images with no image density unevenness for a long period of time, in which the images formed are free from image defects of edge deletions and other deletions therein and which ensures good and uniform developability everywhere in the latent image region to be developed with preventing the latent image support used from being degraded. The method includes a step of forming a latent image on a latent image support, a step of developing the latent image on the latent image support with a two-component developer on a developer support disposed to face the latent image support, and a step of transferring the thus-developed toner image onto a transfer medium, wherein the developer support is a cylindrical sleeve having a diameter of at most 20 mm or the latent image support is a cylindrical sleeve having a diameter of at most 40 mm, and the resistance of the two-component developer is at least 10 &OHgr; in an electric field of 2 V/&mgr;m.
