A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

An image forming apparatus includes an image forming unit, an input unit and a control unit. The image forming unit forms an image by using a plurality of consumables. The input unit receives an input of information designating the consumables to be used for forming the image. The control unit selectably displays other candidates of the consumables to be used for forming the image, based on the designated consumables.

In one example of the disclosure, a first transfer of ink is made from a photoconductor to a blanket in contact with the photoconductor. The blanket is to cycle along a path. The first transfer occurs at a first arc of the blanket path. A second transfer of the ink is made from the blanket to a media in contact with the blanket. The second transfer occurs at a second arc of the blanket path. A heat source located adjacent to a third arc of the blanket path is utilized to heat an external surface of the blanket. The heating is to occur following the second transfer of the ink.

The present disclosure provides an image-forming device, and a method and a controller for controlling the image-forming device. The method is executed by the controller of the image-forming device. The method includes when a first sensor disposed in the image-forming device is abnormal, determining, by the controller, an environmental parameter in real-time through one or more target apparatuses disposed in the image-forming device, where the environmental parameter includes at least one of temperature and humidity; and the first sensor is configured to detect the environmental parameter inside the image-forming device; and according to the environmental parameter in real-time, adjusting, by the controller, a control parameter when the image-forming device forms images.

A toner cartridge includes a customer replaceable unit monitoring (CRUM) apparatus to store error information of a toner injection process of the toner cartridge using a toner refill apparatus. Based on the error information not being stored in the CRUM apparatus, an availability of a refill operation of the toner cartridge is identified based on a predetermined first reference value and an amount of toner detected in the toner cartridge, and, based on the error information being stored in the CRUM apparatus, the availability of the refill operation of the toner cartridge is identified based on a predetermined second reference value and the amount of toner detected in the toner cartridge.

An image forming apparatus includes an image forming unit that has multiple developing units, arranged in series for basic colors in a rotational driving direction of a transfer body, for developing toner images of the basic colors based on input image data and forms the overlapped toner images on a surface of the transfer body in a state in which the toner images are aligned; a transferring unit that transfers the toner images onto a sheet; and a controller that calculates a difference between color information of an image obtained by reading the toner images and color information of the input image data, calculates a color change direction of the toner images with respect to a color of the input image data based on the difference, and refers to a table and determines a shape of a surface of the sheet based on information of the color change direction.
