A sheet sorting apparatus comprising:

a first tray detachable from an apparatus main body;
a second tray arranged vertically below the first tray;
a conveyance unit configured to convey a sheet to either of the first and the second trays;
a tray detection unit configured to detect that the first tray is detached from the apparatus main body;
a stacking amount detection unit configured to detect that an amount of sheets stacked on the second tray reaches a predetermined amount;
and
a control unit configured to control the conveyance unit not to convey the sheet to the second tray, in a case where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount,
wherein the control unit permits the conveyance unit to convey the sheet to the second tray, in a case where the tray detection unit detects that the first tray is detached from the apparatus main body in a state where the stacking amount detection unit detects that the amount of sheets reaches the predetermined amount and conveyance of the sheet to the second tray by the conveyance unit is stopped.
