Abstract
A skew feed or damage in the sheet in automatic feeding is avoided. In an image forming apparatus provided with a printer for recording an image, the printer is provided with a feeding port for enabling manual insert sheet feeding and an automatic sheet feeder (ASF) is detachably mounted on the feeding port to enable automatic sheet feeding through the feeding port. As shown in the drawings, the printer is provided with a printer sheet guide for manual insert sheet feeding, while the ASF is provided with an ASF sheet guide for automatic sheet feeding, and the ASF sheet guide is displaced toward the inner side of the sheet by a predetermined amount with respect to the printer sheet guide. Thus, the sheet automatically fed utilizing the ASF sheet guide does not contact the printer sheet guide, whereby the skew feed of the sheet and the damage to the sheet end can be prevented.
