1. An image forming apparatus comprising:
an image forming unit configured to form an image on an image bearing member based on an image forming condition;
a transfer unit configured to transfer the image formed on the image bearing member onto a sheet;
a first reading sensor configured to read a first image for adjustment which has been formed on the sheet;
a second reading sensor configured to read a second image for adjustment which has been formed on the image bearing member; and
a controller configured to:
generate the image forming condition based on reading results of the first image for adjustment on a plurality of sheets, which are obtained by the first reading sensor; and
generate the image forming condition based on a reading result of the second image for adjustment, which is obtained by the second reading sensor,
wherein the controller is configured to:
determine whether a reading result of the first image for adjustment, which has been obtained by the first reading sensor, is abnormal; and
control, based on a result of the determination, whether to generate the image forming condition based on the reading result of the second image for adjustment, which has been obtained by the second reading sensor, without use of the reading results of the first image for adjustment on the plurality of sheets, which have been obtained by the first reading sensor.
