An image forming apparatus includes an intermediate transfer body, an image forming device including an image carrier (carrier), a developing device that develops an electrostatic latent image on the carrier into a toner image with a two-component developer (toner and carrier), a first transfer device that transfers the toner image onto the intermediate transfer body, and a first cleaning device that cleans the carrier's surface after the transfer process, a second transfer device that transfers the toner image onto a recording medium, a second cleaning device that cleans the intermediate transfer body's surface after the transfer process, a power-supplying device that supplies a developing bias, a first transfer bias, and a second transfer bias to the developing device, the first transfer device, and the second transfer device, respectively, and a controller that controls to perform a toner discharging operation of forming a toner image to be discharged on the carrier.

Image forming apparatus having a controller for controlling toner discharge operation

An image forming apparatus includes at least one imaging device including at least a photoconductor, a charging device, an exposure device, a developing device, and a transfer device; a detector that detects that the photoconductor of the at least one imaging device has reached the end of a life of the photoconductor; and a controller that controls the at least one imaging device under an imaging condition including a charge condition, an exposure condition, a development condition, and a transfer condition. After the controller acquires detection information of the detector, the controller controls the at least one imaging device by changing the imaging condition to a condition that decreases an image quality.

Image forming apparatus for controlling at least one imaging device if an end of a life of a photoconductor is detected

An image forming apparatus includes a body, a developer recovery container, a detecting section, a power supply, a detection object part, a pair of wires, a conducting section, a drive section, and a determining section. The determining section determines the developer recovery container to have been used in a case where the developer is determined to be not present in the detection object part on the basis of information from the detecting section, and in a case where the developer is determined to be present in the detection object part, checks the information from the detecting section again after driving the drive section, and determines the recovery container to have not been used when the developer is determined to be not present in the detection object part and determines the recovery container to have been used when the developer is determined to be present in the detection object part.

Image forming apparatus, image forming system, and computer readable medium

An image forming apparatus includes an image forming unit that forms, on an image bearing member, an image for adjusting operations of the image forming apparatus, a container that contains toner removed from the image bearing member, and a controller that controls formation of the image for adjusting the operations of the image forming apparatus so that after an amount of toner contained in the container reaches a threshold value, an amount of toner removed from the image bearing member and to be contained in the container is reduced to less than before the amount of toner contained in the container reaches the threshold value.

Image forming apparatus and image forming method

An image forming device includes an image holding member and a charging unit. In a case in which an AC current, while being increased, is supplied to the charging unit in a state in which a DC voltage value and an AC voltage value applied to the charging unit are maintained, or a case in which a DC voltage, while being increased, is supplied to the charging unit in a state in which the AC voltage value applied to the charging unit is maintained, a current detection unit detects DC current values. An inflection point derivation unit derives an inflection point of a correlation line representing an correlation between the detected DC current values and the supply amounts. An execution unit executes pre-specified processing when a characteristic value of the derived inflection point reaches a pre-specified value.
