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 developer 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 determines 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; and stops operating the developer based on a determination indicating that the first estimated time period is greater than the first predetermined time period.
