An image forming apparatus includes an image processor configured to convert image data based on a first conversion condition; an image forming unit configured to form an image on a sheet based on the image data converted by the image processor, the image forming unit having an image bearing member on which the image is to be formed, a transfer unit configured to transfer the image from the image bearing member onto the sheet, and a fixing unit configured to fix the image to the sheet; a conveyance roller configured to convey the sheet having the image fixed thereto; a reading unit configured to read a pattern image on the sheet conveyed by the conveyance roller; and a detector configured to detect a pattern image on the image bearing member.

Image forming apparatus

An image forming apparatus to which a sheet treating apparatus is to be connected includes a communication device, having a serial port used for serial communication with the sheet treating apparatus and a parallel port used for parallel communication with the sheet treating apparatus, to communicate with the sheet treating apparatus, and one or more processors. At least one of the one or more processors operates to determine a communication method to communicate with the sheet treating apparatus based on configuration information representing a connection configuration of the sheet treating apparatus, and switch an operation of the serial port such that the serial port of the communication device is used in the parallel communication in a case where a determined communication method is a method in which the parallel communication is performed and the serial communication is not performed.
