Provided is an image forming system which optimizes subsequent processes for crossing paper when a causing apparatus has stopped in the state in which paper is spanning the causing apparatus and a downstream apparatus. The image forming system conveys the paper from a first apparatus (the causing apparatus) to a second apparatus (the downstream apparatus) connected to the first apparatus. The image forming system 1 includes a conveying unit and a hardware processor. The conveying unit conveys the paper. The hardware processor determines, in a case where the paper is normally conveyed by the conveying unit across the first apparatus and the second apparatus, whether processes of the first apparatus has been completed for crossing paper which is the paper spanning the first apparatus and the second apparatus, when the first apparatus stops due to an abnormality.

An image forming apparatus includes an image forming section, a driving unit and an operation unit. The image forming section includes one or more image forming units. The driving unit generates driving force. The operation unit selectively performs a first operation and a second operation. The first operation is an operation to change over from a coupled state of the one or more image forming units and the driving unit, which the driving force is transmitted to the one or more image forming units, to a released state of the one or more image forming unit and the driving unit, which the driving force from the driving unit is not transmitted to the one or more image forming units. When the second operation is performed, the released state is maintained.

In an image forming operation of transferring one developer image to a recording material, when a plurality of image forming portions include a non-image forming portion that is an image forming portion which does not form a developer image on an image bearing member, applying means for applying a charging bias to a charging member which comes into contact with and charges the image bearing member applies a second charging bias to the charging member in the non-image forming portion, the second charging bias having a same polarity as a first charging bias for forming a developer image and being a voltage equal to or lower than a discharge start voltage.

A decoloring apparatus includes a decoloring assembly, a driver configured to drive the decoloring section, and a storage configured to store first setting information, as setting information when there is no next job, and second setting information, as setting information when there is a next job; and a controller. The controller is configured to perform control to drive the decoloring assembly based on conveyance speed and set temperature corresponding to a predetermined, coverage rate of the image receiving medium in the first setting information stored in the storage if there is no next job, or perform control to drive the decoloring assembly based on the conveyance speed and the set temperature corresponding to a predetermined coverage rate of the image receiving medium in the second setting information stored in the storage if there is a next job.

Provided is an image forming apparatus capable of estimating lives of components more accurately than before. The image forming apparatus includes an ion conductive component, and a processor for estimating a life of the conductive component. The processor acquires an index value related to energization of the conductive component, and estimates the life of the conductive component based on the index value per unit time.

An image forming apparatus includes a transfer unit that transfers a toner image to a recording medium; a non-white toner image forming unit that forms a non-white toner image on the transfer unit by using non-white toner having a non-white color that differs from white; a white toner image forming unit that forms a white toner image on the transfer unit by using white toner that is white in color after the non-white toner image is formed on the transfer unit; and a control unit that controls an amount of the white toner used by the white toner image forming unit to form the white toner image so that the amount of the white toner is smaller when the non-white toner image is formed under the white toner image than when no toner image is formed under the white toner image.

A method for adapting a printer for operating with more colours, the printer including an inner framework and a dispenser assembly associable with said framework, includes the steps of application of at least one first quick release connector for electric cables at the dispenser assembly; and application of at least one corresponding second quick release connector at the inner framework of the printer.

In accordance with an embodiment, an image forming apparatus comprises a main body, an attaching/detaching section, an uneven part, and a cleaning member. A conveyance path is formed inside the main body. The attaching/detaching section housed in the main body is detachably drawn out with respect to the main body along the conveyance path. The uneven part has a convex part and a concave part and is arranged in the attaching/detaching section. The cleaning member arranged in the main body is slidable with the convex part in a direction in which the attaching/detaching section moves along the conveyance path.

An image reading apparatus comprises a housing having a document table glass, a scanner section, a cover member, an adsorption board, a driving section and a controller. The cover member is connected to the housing to be rotatable around a first rotation center line with respect to the housing between a closed position where the document table glass is covered and an open position. The adsorption board, arranged in a part at a housing side at the time the cover member is positioned at the closed position, has an adsorption surface adsorbing the original document, and is connected to the cover member to be rotatable around a second rotation center line parallel to the first rotation center line. The driving section adsorbs the original document on the adsorption surface of the adsorption board.
