摘要： An image forming unit forms an image on a sheet. A reverse unit pulls in the sheet from a main conveyance path and reverses a conveyance direction of the sheet to feed the sheet to a sub-conveyance path. A control unit causes a conveyance unit to convey a first sheet that is waiting to the main conveyance path after a trailing end of a second sheet that has been fed from a feeding unit and follows the first sheet has passed through a merging point, and moves a trailing end of the first sheet downstream of a branch point before the second sheet reaches the branch point.

摘要： An image forming apparatus includes: a photosensitive member configured to be rotated; scanning means for scanning, by light corresponding to image data, the photosensitive member that is charged, thereby forming an electrostatic latent image on the photosensitive member; and a contacting member in contact with the photosensitive member to form a nip portion. In a correction mode in which a shift of an image is corrected based on a detection result obtained by detecting, at the nip portion, an electrostatic latent image for correction formed on the photosensitive member by the scanning means, a width of the electrostatic latent image for correction is equal to or more than a width of the nip portion in a rotation direction of the photosensitive member.

摘要： An image forming apparatus includes a stack portion having recording materials, an image forming unit, a basis weight detection unit, an operating sound detection unit, and a mode selection unit. The basis weight detection unit detects a recording material basis weight based on an ultrasonic wave. The operating sound detection unit detect an abnormality of a generated operating sound. The mode selection unit selects, for each recording material fed to the image forming unit, between transmitting to the basis weight detection unit a first instruction for detecting the recording material basis weight and transmitting to the operating sound detection unit a second instruction for detecting the operating sound abnormality. In determining an interval at which each second instruction is transmitted, the mode selection unit determines the interval so that the interval and a cycle, in which properties of recording materials on the stack portion are repeated, do not continuously coincide.

摘要： A control apparatus includes a prediction unit configured to repeatedly predict a first target value based on prediction information; a transmission/reception unit configured to repeatedly transmit the prediction information to a server and receive a second target value having higher prediction accuracy than the first target value predicted by the server; a management unit configured to update a first error of prediction in the prediction unit based on the second target value and the first target value; and a setting unit configured to set a control target value based on the first target value and the first error. A first time interval in which the prediction unit repeatedly predicts the first target value is shorter than a second time interval in which the transmission/reception unit repeatedly transmits the prediction information to the server.
