Abstract: An image forming apparatus includes an image forming portion, an exposure device, an image density sensor, and a control portion. The control portion can, by adjusting the development voltage based on the image density of a reference image and the amount of exposure from the exposure device, perform image density correction to adjust the image density. The control portion predicts the toner charge amount based on a formation condition of the reference image and the image density of the reference image and determines the timing of performing the image density correction next time based on the rate of change of the toner charge amount calculated using a first toner charge amount predicted when the image density correction was performed last time, a second toner charge amount predicted when the image density correction is performed this time, and the interval between the image density correction performed last time and this time.

Abstract: An image forming apparatus includes an adjustment processing portion, an acquisition processing portion, and a determination processing portion. Each time an adjustment condition is satisfied during execution of an image forming process, the adjustment processing portion uses toner to adjust one adjustment target selected in accordance with a specific order among a plurality of adjustment targets related to image quality of an output image output by the image forming process. The acquisition processing portion acquires variation amount information related to an amount of variation in a state value related to an image forming portion caused by a start of the image forming process. The determination processing portion determines an adjustment target to be adjusted first after the start of the image forming process by the adjustment processing portion, based on the variation amount information acquired by the acquisition processing portion.

Abstract: An object is to enable management work such as maintenance of parts of a printing apparatus in an integrated manner. An apparatus according to the present disclosure obtains: first condition information indicating a condition of a constituent part of a printing apparatus, specified based on a life of the part; and second condition information indicating a condition of the part specified based on a scanned image obtained by reading a print medium on which an image has been formed by the printing apparatus. The apparatus further generates a display image representing the condition of the part indicated by the first condition information and the condition of the part indicated by the second condition information, and outputs a signal representing the display image.

Abstract: In the image forming method, a halftone image is generated by performing halftone processing for an input image, a scanned image of a printed material on which on which the halftone image is printed is obtained, and a failure component of an image forming apparatus is identified based on a difference between the scanned image and the input image. In the generation, the halftone image is generated by representing a dot pattern of a halftone portion in a case where the input image is a test image for the failure diagnosis by a dot pattern whose frequency is relatively higher than that of a dot pattern that is applied to the halftone portion in a case where the input image is an image other than the test image.
