Abstract
An image forming apparatus including a sheet feeding device that is driven by a driving device through an interval device. The interval device can transfer the driving force only when a coil in the interval device is not electrified. Accordingly, when the feeding device is in active condition, the coil and the interval device do not become hotter and sheet feeding becomes more reliable.
