1. An image forming system comprising:
a computer terminal configured to:
receive a print instruction for a print job from a user; and
transmit print job data to a management server;

the management server, wherein the management server is configured to:
receive the print job data from the user computer terminal;
store the print job data as a queue to be printed;
extract the print job data from the queue in accordance with a priority; and
transmit the extracted print job data to a digital front end (DFE);

the DFE, wherein the DFE is configured to:
receive the extracted print job data from the management server;
convert the extracted print job data into image data, wherein the image data comprises data of the cyan, magenta, yellow, and black (CMYK) format;
transmit the converted print job data to an image forming apparatus;

the image forming apparatus, wherein the image forming apparatus comprises:
a memory, wherein the memory is configured to:
receive the converted print job data from the DFE;
store an identifier for identifying a defective page for each print job and an identifier for identifying a print job that includes the defective page in association with each other; and

processing circuitry configured to:
generate a master image by converting the converted print job data from the CMYK format into red, green, and blue (RGB) format;
determine whether a page included in the print job is a defective page, based on the generated master image and the identifier for identifying the defective page;
determine, based on the determination of whether the page included in the print job is a defective page, whether the converted print job data is data of a print job to be reprinted; and
in response to determination that the converted print job data is data of a print job to be reprinted, perform control to eject a first conveyance medium including a page not determined to be defective to a first ejection destination, eject a second conveyance medium including a defective page to a second ejection destination, print an image of the defective page on a third conveyance medium, and eject the third conveyance medium on which the image is printed to the first ejection destination.
