Abstract
An exposure device forms an electrostatic latent image on a photoconductor drum. A charging device charges the photoconductor drum with a charging bias. A development roller holds toner with a development bias and attaches the toner to the electrostatic latent image. A toner image is obtained by attaching the toner to the electrostatic latent image and primarily transferred onto an intermediate transfer member. A determining unit primarily transfers to the intermediate transfer member non-image toner attached on the photoconductor drum while the charging bias and the development bias are increased before image forming and/or while the charging bias and the development bias are decreased after image forming, and determines an amount of the non-image toner on the basis of an output of a sensor. A managing unit determines a toner consumption amount or a toner residual amount with taking the determined amount of the non-image toner into account.
