ABSTRACT:
A sheet-feeding device for separating sheets stored in a sheet storage unit by blowing air heated by a heater toward the sheets includes a controller which detects an abnormality when a heater temperature does not reach a first predetermined temperature within a predetermined time. The controller continues to control the heater temperature but stops determining whether or not the heater temperature is increased to the first predetermined temperature within the predetermined time when it is detected that the sheet storage unit is in an open state.
