A sheet separating and feeding unit incorporable in an image forming apparatus includes an image forming device, a sheet container, a sheet feeding unit including an endless, dielectric belt and an electric potential pattern forming unit, a belt supporting mechanism including a first supporting roller and a second supporting roller, and a moving unit. The first supporting roller rotates to rotatably move the second supporting roller between a sheet attracting position and a sheet feeding position so that the flat portion of the dielectric belt moves between the sheet contact position and the sheet pick-up position.
