Abstract
A paper feeder for an image forming apparatus, which includes an intermediate tray for temporarily accommodating a paper having an image already formed on at least one side thereof, a paper feeding roller for feeding out the paper stored in the intermediate tray, a first support for supporting the paper feeding roller in such a manner as to be moved between a paper feeding position at which the paper feeding roller is allowed to contact the paper and a retracting position at which the paper feeding roller is separated from the paper. An oblique travel preventing roller is also provided, disposed parallel to the axis of the paper feeding roller and adapted to prevent the paper from being advanced obliquely. A second support supports the oblique travel preventing roller in such a manner as to be moved between the paper feeding position at which the oblique travel preventing roller is allowed to contact the paper and the retracting position at which the oblique travel preventing roller is separated from the paper. A driving mechanism moves the paper feeding roller and the oblique travel preventing roller to the retracting position.
