A charged positive toner having a positive polarity that attaches to a charge roller is moved from the charge roller to a photosensitive drum, and the positive toner is transferred to an intermediate transfer belt at a primary transfer portion at which a primary-transfer power supply forms an electric potential having a negative polarity. The primary-transfer power supply forms an electric potential having the positive polarity at the primary transfer portion, and the positive toner transferred to the intermediate transfer belt is moved together with the intermediate transfer belt and is collected by the charge roller in contact with a downstream photosensitive drum.

According to an embodiment, an image processing system includes an image forming unit, a decoloring unit, a storage device, an operation panel and a processor. The storage device stores image data of a plurality of printed materials. The processor forms on a sheet an image based on image data in a page range of the printed material received by the operation panel. The processor determines whether or not images of all pages in the page range have been decolored in a predetermined range after the image formation is executed when the formed image is decolored by the decoloring unit.

An image forming apparatus includes an image forming section and a transfer section. The image forming section includes a first image forming unit that forms a first developer image and a second image forming unit that forms a second developer image. The transfer section transfers, on a basis of a first transfer condition, the first developer image onto a medium, and transfers, on a basis of a second transfer condition, the second developer image onto the medium onto which the first developer image has been transferred. The second transfer condition is different from the first transfer condition.

A storage portion (15) stores one or more pieces of automatic process setting information (20) including detection target information and processing content corresponding to the detection target information, the detection target information composed of a specific character string, a specific figure, or a specific combination thereof. An image data acquiring portion (161) acquires image data of a document (30). A detection processing portion (162) detects the detection target information from the document (30) based on the image data. A process executing portion (163) processes the image data according to the processing content included in the automatic process setting information (20), when the detection target information included in the automatic process setting information (20) is detected from the document (30) by the detection processing portion (162).

Provided is an image forming system that can generate the data of variable data printing, easily. Image forming system X includes A printing a terminal and an image forming apparatus. The terminal includes a form making part, a layer setting part, and a display part. The form making part generates a form data for variable data printing in which a plurality of objects is arranged. The layer setting part sets overlapped object where the object for a reference is behind as a semi-transparent layer. The display part superimposes the object set as the semi-transparent layer set up by the layer setting part, and corresponding variable data.

An image forming apparatus, in which an image forming method is performed, includes an image forming device to form an image on a recording medium, a reading device to scan the recording medium having a mark and generate a scanned image, and circuitry to calculate a correction value to adjust a position of the image to be formed on the recording medium, based on the scanned image. The circuitry calculates the correction value to adjust a position of an image to be formed on a second face of the recording medium based on a first scanned image generated from a first face of the recording medium, within a period from when the first scanned image is generated from the first face to when the image starts to be formed on the second face.
