In an image forming apparatus, in a case in which a second toner image to be transferred to a same recording material as a first toner image is to be transferred is formed on the photosensitive member after the first toner image is formed on the photosensitive member and the first toner image is formed on an area of the photosensitive member including at least a part of a position of the second toner image one cycle before with respect to a movement direction of the surface of the photosensitive member, a control unit changes a value of a transfer current at a time of transferring the first toner image to a transfer-receiving member between a first value and a second value of which an absolute value is greater than an absolute value of the first value, based on image information regarding the second toner image.

An image forming apparatus includes a latent image bearer, a toner image forming unit, an intermediate transfer member, a primary transfer member, a secondary transfer member, a switching unit, and control circuitry. The toner image forming unit forms toner images on the latent image bearer. The primary transfer member transfers the toner images on the latent image bearer onto the intermediate transfer member. The secondary transfer member transfers the toner images on the intermediate transfer member onto recording materials. The switching unit switches a position of one of the secondary transfer member and the intermediate transfer member between a first and a second position. The control circuitry controls at least one of a first and a second operation. The control circuitry changes at least one of the first and the second operation when the toner images satisfy a specified abnormal image reduction condition at a first and a second timing.

An image forming apparatus includes a first processor configured to control a transporter that transports a sheet and a first image forming section that forms an image on the sheet transported by the transporter, and a second processor configured to control a second image forming section that forms an image on the sheet transported by the transporter. The first processor and the second processor are contained in a single housing. The first processor is configured to perform transport preparation for transporting the sheet at the transporter and receive, from the second processor, a completion notification corresponding to a preparation command, for performing image formation preparation in the second image forming section, transmitted to the second processor via an inside of the housing, and subsequently cause the transporter to transport the sheet and the first image forming section to form the image.

An image forming apparatus is used, which includes: a scanning unit that scans a surface of a photosensitive member with light and forms a latent image according to image data; a developing unit that supplies toner to the latent image to develop the latent image; a fixing unit that heats and fixes the toner image on a recording material; and a control unit that controls a fixing temperature based on the image data, wherein the control unit analyzes a printing ratio by dividing the image data into a plurality of regions in a main scanning direction when the scanning unit scans the surface of the photosensitive member with light, and determines the fixing temperature on the basis of the position in the main scanning direction and the printing ratio for each of the plurality of regions.

A printed material, an image forming apparatus, and a data acquisition device. The printed material includes a printed confidential information image visible under a special condition, and an information image having information on a position of the confidential information image. The image forming apparatus includes an image forming device configured to form an image on a recording medium to form the printed material. The data acquisition device includes circuitry, and the circuitry is configured to acquire confidential information from the confidential information image on the printed, specify the position of the confidential information image from the information image, and display position information of the confidential information image.

An image forming apparatus includes a latent image bearer, a toner image forming unit, an intermediate transfer member, a primary transfer member, a secondary transfer member, a switching unit, and control circuitry. The toner image forming unit forms toner images on the latent image bearer. The primary transfer member transfers the toner images on the latent image bearer onto the intermediate transfer member. The secondary transfer member transfers the toner images on the intermediate transfer member onto recording materials. The switching unit switches a position of one of the secondary transfer member and the intermediate transfer member between a first and a second position. The control circuitry controls at least one of a first and a second operation. The control circuitry changes at least one of the first and the second operation when the toner images satisfy a specified abnormal image reduction condition at a first and a second timing.

An image based correction system compensates for the image quality artifacts induced by thermal ghosting. With thermal ghosting directly tied to previous image content, a feed forward control system predicts the thermal ghosting artifact based on the images previous printed and generates an open loop, 2-D correction to the gray-level image that mitigates the undesirable ghosting artifacts. For example, the correction system compensates for the thermal ghosting by making the current digital image “lighter” in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions.

Example implementations relate to first page out reduction. For example, a system according to the present disclosure may include a host computing device including a processor. The system may further include a printer coupled to the host computing device. The processor may determine a distribution of print content relative to a leading edge of a page of print medium. The processor may further determine a first threshold fuser temperature in response to the determination of the distribution of print content.

Downtime relating to formation and detection of a detection image is reduced. An image forming apparatus includes a controller configured to calculate a first conversion unit to convert a gradation of input image data so that density output for the input image data becomes a first density output characteristic based on a first detection result of the detection image detected by a density sensor in a first mode. The controller generates a second conversion unit to convert the gradation of the input image data so that the density output for the input image data becomes a second density output characteristic in a second mode based on the detection result in the first mode and correction information, and further updates the correction information based on a second detection result of the detection image detected by the density sensor in the second mode and the first detection result.

A print control apparatus includes a completion condition obtaining unit and a management unit. The completion condition obtaining unit obtains, when executing a print job for printing one or more pages satisfying a predetermined condition, a completion condition of the print job. The management unit manages the print job as uncompleted until the obtained completion condition is satisfied even when a recording material on which the one or more pages are printed is ejected.
