Abstract:
A sheet feeder, which is incorporated in an image forming apparatus, includes an endless attraction belt that is rotatably disposed facing a top surface of a sheet stack, a belt charger to attract an uppermost sheet of the sheet stack, and a sheet separator to press the attraction belt against the sheet stack, bend a contact region to which the uppermost sheet is attracted and contacted to the attraction belt, and separate the uppermost sheet from a subsequent sheet or other sheet of the sheet stack. In this configuration, a curvature of a contact surface of the sheet separator with respect to the attraction belt is changeable.
