Abstract
An image forming unit suppressing occurrences of jitters, includes an image carrier rotating by drive force transmitted via a first route to form an electrostatic latent image, and a developer carrier having an elastic layer carrying a developer on a surface thereof and rotating by drive force transmitted via a second route to develop the electrostatic latent image. The electrostatic latent image is developed with the developer under a development condition that, with the elastic layer of a thickness from 0.5 mm to 2.5 mm, the developer carrier is rotated with a circumferential speed ratio to the image carrier in a range from 1.10 to 1.45, or that, with the elastic layer of a thickness more than 2.5 mm but not more than 5.0 mm, the developer carrier is rotated with a circumferential speed ratio to the image carrier in a range from 1.10 to 1.24.
