## Abstract

An image forming apparatus using an image forming unit configured to form an image on a sheet and a display unit configured to display information includes at least one controller, the at least one controller configured to function as a management unit configured to manage print data in association with user information, the management unit configured to discriminably manage information about previously-printed print data and information about unprinted print data, and a unit configured to display on the display unit a user selection screen on which a plurality of selection objects corresponding to the user information is arrangeable and on which the selection object corresponding to the user information associated with the unprinted print data is arranged while no selection object corresponding to the user information associated with the previously-printed print data but not associated with the unprinted print data is arranged.

## Claims

### Claim 1

An image forming apparatus using an image forming unit configured to form an image on a sheet and a display unit configured to display information, the image forming apparatus comprising:
at least one controller having a processor that executes programs stored in a memory device, the at least one controller configured to function as:
a management unit configured to manage print data in association with user information, the management unit configured to discriminably manage information about previously-printed print data and information about unprinted print data; and
a unit configured to display on the display unit a user selection screen on which a plurality of selection objects corresponding to the user information is arrangeable and on which the selection object corresponding to the user information associated with the unprinted print data is arranged while no selection object corresponding to the user information associated with the previously-printed print data but not associated with the unprinted print data is arranged.
