1. An image forming apparatus comprising:
an image processor configured to convert image data based on a conversion condition;
an image forming unit configured to form an image based on the image data converted by the image processor as converted image data, the image forming unit having a replaceable member;
a memory configured to store the image data and the converted image data;
a sensor configured to perform measurement of a test image formed by the image forming unit; and
a controller configured to:
detect a replacement of the replaceable member;
in a case where the replacement of the replaceable member is detected while the image forming apparatus is forming images based on a job, control the image forming unit to form the test image;
generate the conversion condition based on a result of the measurement of the test image performed by the sensor; and
in a case where the replacement of the replaceable member is detected while the image forming apparatus is forming the images based on the job, control the image processor to convert the image data stored in the memory based on the generated conversion condition.
