Abstract

See full text

An image forming apparatus, including: an image forming control portion; a stacking portion; a sheet feeding unit; a change unit configured to change a state of the sheet feeding unit between a first state in which the sheet feeding unit is in abutment with the recording medium stacked on the stacking portion and a second state in which the sheet feeding unit is separated away from the recording medium; a decision unit configured to decide a size of the recording medium stacked on the stacking portion; and a control unit configured to control the change unit so that, when the size of the recording medium is changed from an undecided state to a decided state by the decision unit, the state of the sheet feeding unit is changed from the second state to the first state even without an instruction to start image formation from the image forming control portion.
