Abstract
An image forming apparatus includes an image forming unit and a reading unit. The image forming unit is configured to form an image. The reading unit has a first reading mode, in which a document conveyed by a conveyance unit is read, and a second reading mode, in which a document placed on a platen glass is read. A first correction mode, in which correction data is generated using a result of reading the test document in the first reading mode, or a second correction mode, in which correction data is generated using a result of reading the test document in the second reading mode, is executed based on a result of detection of placement of a test document on the reading unit.
