1. An image forming apparatus, comprising:
a feeder including a tray, on which a sheet is to be placed, the feeder being configured to convey the sheet on the tray;
a reader including a platen, on which a sheet is to be placed, the reader being configured to read the sheet on the platen, and to read the sheet conveyed by the feeder;
an image forming unit configured to form a test pattern;
a controller configured to:
control the image forming unit to form the test pattern on a sheet;
control the reader to read the sheet having the test pattern formed thereon; and
control based on a result of reading the sheet having the test pattern formed thereon, a density of an image to be formed by the image forming unit; and
a display,
wherein the controller allows, in a case where a sheet of a first type having the test pattern formed thereon is placed on the platen, a first reading process in which the reader reads the sheet on the platen,
wherein the controller allows, in a case where a sheet of the first type having the test pattern formed thereon is placed on the tray, a second reading process in which the feeder conveys the sheet on the tray so that the reader reads the sheet on the tray,
wherein the controller allows, in a case where a sheet of a second type having the test pattern formed thereon is placed on the platen, the first reading process in which the reader reads the sheet on the platen,
wherein the controller controls the display, in a case where a sheet of the second type having the test pattern formed thereon is placed on the tray, to display a screen for prompting the sheet on the tray to be placed on the platen on the display without allowing the second reading process, and
wherein the first type is different from the second type.
