发明名称 Sheet feeding apparatus with sheet lifting member and image forming apparatus
摘要 A sheet feeding apparatus has a sheet loading plate, a sheet feeding member, a side regulating member on the sheet loading plate and a torsion spring to generate an elastic biasing force, so as to bias the sheet loading plate to bring the uppermost sheet into contact with the sheet feeding means. The torsion spring biases the sheet loading plate so that a torsion moment generated by the end-arm portions of the torsion spring is made variable depending on a position of other of the end-arm portions engaged with the side regulating member.
