An Image forming apparatus comprising:
- a printer configured to print an image;
- a reading unit having:
- a platen on which a document is to be placed;
- and
- a reading sensor configured to read an image of the document placed on the platen,
- a document feeder rotatably supported by the reading unit having:
- a stacking tray on which a document is to be stacked;
- a conveyance unit configured to convey the document stacked on the stacking tray to cause the reading sensor to read an image of the document;
- and
- a discharge tray on which the document conveyed by the conveyance unit is discharged,
- a display;
- and
- a controller configured to:
- receive user instruction information for instructing to print the test chart;
- control the printer to print the test chart on a sheet in a case where the user instruction information is received;
- display a screen for selecting a reading mode for reading the test chart among a plurality of reading modes after the user instruction information is received;
- control the conveyance unit and the reading sensor to read the test chart on the sheet while conveying the sheet stacked on the stacking tray in a case where a first reading mode, which is included in the plurality of reading modes, is selected on the screen;
- control the reading sensor to read the test chart on the sheet on the platen in a case where a second reading mode, which is included in the plurality of reading modes, is selected on the screen;
- and
- control density of the image to be printed by the printer based on a reading result of the test chart by the reading sensor.
