Image forming apparatus and method for prefeeding a sheet to a conveying path from a sheet accommodating device prior to generation of a sheet feeding signal

摘要

An image forming apparatus and method includes a sheet accommodating device, a feeder, an image former, a sheet conveying path, and a controller. The sheet accommodating device accommodates a stack of sheets. The sheet accommodating device is movable in a direction crossing with the feeding direction for the sheets. The feeder feeds one-by-one the sheets from the sheet accommodating device. The image former forms an image on a sheet sent from the sheet accommodating device by the feeder. The sheet conveying path has a sufficient length to retain the sheet from the sheet accommodating device between the feeder and the image former so that a trailing edge of the sheet is downstream of the feeder. The controller pre-feeds the sheet to the sheet conveying path from the sheet accommodating device prior to the generation of a sheet feeding signal.
