Publication number: 20160098005Abstract: An image forming apparatus includes a plurality of latent image bearers, a latent image writer, a plurality of developing units, a primary transfer unit, a secondary transfer unit, an adjuster, a pattern image formation controller, a color deviation detector, a color deviation correction controller, and an image-formation-mode setting unit. The latent image writer writes latent images to the latent image bearers. The plurality of developing units develops the latent images of the latent image bearers and form toner images of different colors. The primary transfer unit transfers the toner images on the latent image bearers to an intermediate transferer. The secondary transfer unit transfers the toner images from the intermediate transferer to a sheet. The adjuster causes the intermediate transferer and the secondary transfer unit to be in a contact state or a separated state.Type: ApplicationFiled: September 28, 2015Publication date: April 7, 2016Inventors: Kazuhiro KOBAYASHI, Toshiyuki Uchida, Kaoru Yoshino, Toshihiro Shimada
