An electric pencil sharpener, comprises a base, a powering device, a feeding subassembly, a cutter subassembly and an adjusting subassembly. Two brackets ( 31, 32 ) are mounted on the base, standing face to face. Each of the brackets defines two guideways ( 35 ) therein. The powering device is attached to the base. The feeding subassembly comprises a feeding gear module and a pair of feeding rollers ( 23, 24 ). The feeding rollers are respectively supported in guideways between the brackets. The feeding gear module driven by the powering device makes one of feeding rollers to rotate therein. The adjusting subassembly encompasses the feeding rollers on the bracket. The adjusting subassembly pushes the feeding rollers to move along the guideways. With restriction of the guideways, the distance between the two feeding rollers alters so that pencils with different size can be automatically fed and processed.
