摘要：
An image apparatus is provided with a bottom take-out type automatic paper feeding mechanism. Documents are sequentially taken out from a lowermost document by coaction of a paper feeding roller and a document separation pad which is elastically pressed against the paper feeding roller. A hopper is provided on which the documents are placed by stacking. Projections are provided on a document placement surface of the hopper or a paper feeding passage. The projections prevent the documents from being adhered to the hopper which has been electrostatically charged.
