1. An image forming apparatus comprising:
a plurality of sheet storage sections configured to store sheets;
an image forming device configured to form an image on a sheet supplied from one sheet storage section of the plurality of sheet storage sections; and
one or more controllers configured to function as:
a first unit configured to detect an update action performed by sheet replenishment or sheet replacement for one or more sheet storage sections of the plurality of sheet storage sections, wherein each sheet storage section of the plurality of sheet storage sections is respectively set, by a user operation, whether or not to execute a process for prohibiting a predetermined image forming processing when the update action is detected, until a predetermined time period elapses; and
a second unit configured to automatically prohibit the predetermined image forming processing using the one or more sheet storage sections for which the user has set to execute the process for prohibiting the predetermined image forming processing and the update action is detected until the predetermined time period elapses after detection of the update action, and automatically permit the predetermined image forming processing using other sheet storage sections of the plurality of sheet storage sections of the plurality of sheet storage sections for which the update action is not detected,
wherein the predetermined image forming processing is a process of causing the image forming device to form a predetermined image for measuring the position of the formed image on a sheet.
