摘要： An image forming apparatus includes a latent image bearer; a developing device containing two-component developer and including a developer bearer, a development voltage source, and a toner concentration detector; a toner supply device to supply toner to the developing device; a transfer device; and a controller to keep a toner concentration in the developer in the developing device at a target toner concentration during image formation. The controller executes forced toner consumption in which the developing device supplies the toner to the latent image bearer the toner at a predetermined forced toner consumption timing, while inhibiting the toner supply device from supplying toner. When the toner concentration falls to a prescribed toner density lower than the target toner concentration, the controller completes the forced toner consumption and executes a post-consumption toner supply operation.

摘要： An image forming apparatus includes multiple image forming units each including a latent image bearer and a developing device, a transfer device to transfer toner images from the latent image bearers onto a surface of endless rotary member, a cleaner to clean the surface of the endless rotary member, and a control unit to execute a forcible toner consumption process to forcibly consume degraded toner stored in applicable one or more developing devices. The forcible toner consumption process includes a step of forming a toner image formed for forced consumption in a non-image region of the latent image bearer with an amount of toner corresponding to a difference between an image area ratio of a developed image and a prescribed threshold thereof when the image area ratio of the developed image is lower than the prescribed threshold.

摘要： A toner pattern for detecting the degree of toner deterioration is created on a photosensitive element and transferred to an intermediate transfer belt by a primary transfer unit under a transfer condition different from that at the time of image formation. A toner adhesion amount detection unit detects the toner adhesion amount of the toner pattern at multiple places. A degree-of-toner-deterioration calculation unit calculates the degree of toner deterioration on the basis of the variation in data of the toner adhesion amount at multiple places detected by the toner adhesion amount detection unit. A background potential determination coefficient in a process control unit is controlled on the basis of the degree of toner deterioration calculated by the degree-of-toner-deterioration calculation unit.

摘要： An image forming apparatus includes an image bearing member, a toner image forming device, an intermediate transfer member, a primary transfer device, a toner adherence detector, a secondary transfer device, and a controller. The toner image forming device forms a toner image and a toner pattern for detection of degradation of toner on the image bearing member. The primary transfer device transfers the toner pattern onto the intermediate transfer member with transfer conditions that deliberately reduce transfer efficiency compared with that for image formation. The toner adherence detector detects an amount of toner adhered to the toner pattern at multiple places. The controller calculates a degree of degradation of toner based on the difference in the amount of toner adhered to the toner pattern detected by the toner adherence detector and adjusts secondary transfer conditions for the secondary transfer device based on the obtained degradation of toner.

摘要： An image forming apparatus includes: an image forming device to form a toner image onto a recording medium by transferring the toner image directly or indirectly onto the recording medium, the image forming device including a developing unit to develop a latent image formed on an image carrier into the toner image; and a controller to control the image forming device. The controller is to determine whether a first estimated time period is greater than a first predetermined time period, the first estimated time period being a time period from a time when image formation of one page of the image completes to an estimated time when image formation of a subsequent page of the image will start; stop operating the developing unit based on a determination indicating that the first estimated time period is greater than the first predetermined time period; determine, after determination of a time when image formation of the subsequent page of the image starts, whether an updated first estimated time period reflecting the determined time when image formation of the subsequent page of the image starts, is equal to or less than the first predetermined time period; and start operating the developing unit based on a determination indicating that the updated first estimated time period is equal to or less than the first predetermined time period.
