1. An image forming apparatus comprising:
an image forming unit configured to form an image on a sheet;
an image processing unit configured to perform processing, which comprises correction of color misregistration, on image data for controlling the image forming unit to form the image; and
a controller configured to instruct the image forming unit to perform calibration in a case where a component of the image forming unit is replaced,
wherein the image forming unit includes a storage unit, and is configured to acquire correction information to be used for the correction of color misregistration in the calibration to store the correction information in the storage unit,
wherein the image processing unit includes a memory configured to store first image data, which is the image data before being processed, and second image data, which is obtained by compressing the image data after being processed,
wherein, in a case where the calibration is unexecuted, the controller is configured to control the image forming unit to form an image based on the second image data stored in the memory, and
wherein, in a case where the calibration has been executed, the controller is configured to control the image forming unit to update the correction information stored in the storage unit, control the image processing unit to process the first image data based on the updated correction information, and control the image forming unit to perform image formation based on the processed first image data.
