Abstract
A sheet supporting plate is vertically movably provided in a sheet feeding cassette, and a controller controls a lifting and lowering mechanism which lifts and lowers the sheet supporting plate based on basis weight information from an inputting portion. The controller stops the sheet supporting portion at a position where an abutting force causing a feeding roller biased by a feeding roller pressure spring to abut against a sheet is increased as the basis weight of the sheet is increased.
