Image forming apparatus which receives an instruction to take out sheets stored in a storage portion

An image forming apparatus comprising:

• a main body formed with an opening;
• a storage portion configured to store a sheet, on which an image is formed, inside the main body;
• a conveyance unit configured to convey the sheet, on which the image is formed, to the storage portion;
• a moving unit configured to move the sheet stored in the storage portion and stop the sheet in an exposed state in which a part of the sheet is exposed outside the main body through the opening;
• and
• a detection unit configured to detect the sheet in the exposed state,
• wherein, in a case where the image forming apparatus receives a first instruction to convey a first number of sheets, which is more than a storable number in the storage portion, to the storage portion, the conveyance unit conveys a second number of sheets, which is equal to or less than the storable number in the storage portion, to the storage portion, and then in a case where the image forming apparatus receives a second instruction to take out the sheets stored in the storage portion, the moving unit moves the second number of sheets being stored in the storage portion, and stops the sheets in the exposed state and then in response to the detection unit detecting that the second number of sheets in the exposed state is taken out from the storage portion, even if the image forming apparatus doesn't receive any further instruction to convey sheets or further instruction to take out sheets, the conveyance unit and the moving unit repeats an operation to convey rest of the sheets other than the second number of sheets among the first number of sheets to the storage portion and to move the rest of the sheets being stored in the storage portion and stop the rest of the sheets in the exposed state.
