A sheet feeding apparatus having a sheet support for supporting sheets, a rotatable sheet supply roller for feeding out the sheets supported by the sheet support, a first biasing mechanism for biasing the sheet support to generate pressure between the sheets and the rotatable sheet supply roller, a separating device for separating the sheets between the separating device and the rotatable sheet supply roller, a second biasing mechanism for biasing the separating device to generate pressure between the separating device and the rotatable sheet supply roller and a pressure releasing mechanism for releasing the pressures generated by the first and second biasing mechanisms after the sheets are separated by the separating device. The present invention further provides an image forming system with the above-mentioned sheet feeding apparatus and an image forming mechanism for forming an image on the sheet separated by the separating device.
