Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes a position detector configured to detect a position of a sheet, a sheet conveying body, a fixed body, a movable body configured to move, relative to the fixing body, between a first position and a second position different from the first position, and an index mounted on the fixed body. The sheet conveying device further includes a data storing device, a conveyance positional deviation calculator configured to calculate a positional deviation amount of the sheet to the reference sheet conveyance position, a detected positional deviation calculator configured to calculate a positional deviation amount of the position detector to the index based on a result of the position detector, and a reference position detector configured to correct the reference sheet conveyance position based on a result of the detected positional deviation calculator.

Abstract: An image forming apparatus includes an image forming device configured to form a. first image on a first side of a recording medium and a second image on a second side of the recording medium, a position detector configured to detect respective positions of the first and second images, and a controller configured to perform, based on detection results obtained by the position detector, at least one of an image position correction by matching the first and second images and a magnification error correction by calculating and correcting a magnification error of one of the first and second images relative to the other. A program product used in the image forming apparatus includes a method of forming the first image and the second image, detecting the respective positions of the first and second images, and matching a position or a size of the first and second images.

Abstract: A sheet conveying device, which is included in an image forming apparatus and a post processing device, includes a position corrector and either one of a rolling body and a contact resistance reducer. The position corrector is configured to convey a sheet and correct a position of the sheet. The rolling body is disposed at least one of an upstream side and a downstream side of a sheet conveyance passage from the position corrector in a sheet conveying direction and is configured to roll in at least a direction intersecting the sheet conveying direction. The contact resistance reducer is configured to reduce contact resistance generated due to contact of the sheet to a neighboring part when the position of the sheet is corrected by the position corrector.
