Abstract:
A development method, comprising:providing a developer carrier which carries a toner-containing developer held on the surface thereof; providing an image carrier which carries an electrostatic latent image formed on the surface thereof; and opposing the developer carrier to the image carrier in a development region to perform development of the electrostatic latent image formed on the image carrier using the developer held on the developer carrier to form a toner image on the image carrier, wherein the development is performed under a condition that satisfies the following relation |Q2|âˆ’|Q1|/|Q1|&lE;Â±0.45 where Q1 denotes an average amount of charge on toner immediately after passed through a region between the developer carrier and the image carrier opposed thereto when a potential difference between the developer carrier and the image carrier surface is equal to 0V, and Q2 denotes an average amount of charge on toner immediately after passed through the region between the developer carrier and the image carrier opposed thereto when a development voltage is applied to the developer carrier and a potential on the image carrier surface is equal to a potential on a non-image section.
