Abstract: An image forming apparatus of the present invention has a photosensitive drum for carrying an electrostatic latent image, an image forming section for forming the electrostatic latent image on the photosensitive drum, a developing unit for supplying a developing agent to the electrostatic latent image formed by the image forming section, a transfer charger for transferring a developing agent image which is developed by the developing unit to a sheet, supplying mechanism for supplying the sheet to the photosensitive drum, and a control section for allowing a plurality of electrostatic latent images to be formed at a time in a parallel sheet array on the photosensitive drum as required through an image forming mechanism, in which the supplying mechanism has a supplying section for holding sheets in a parallel array as required and first and second supply sections for allowing the sheets which are held in a parallel array to be picked up in units of one sheet in a parallel array at a time and supplying these par
