发明名称 IMAGE FORMING DEVICE
摘要 PURPOSE:To shorten a carrying path for refeeding a sheet and to eliminate the need of a by-pass carrying path by refeeeding a transfer sheet whose one- surface is completely transferred without being stacked on a stacking means, when the set value of a number of both surface transfer sheets setting means is one, that is, the number of the transfer sheets whose both surface is transferred is one. CONSTITUTION:A number of sheets setting part 102 is provided on a controller 101, and the number of the transfer sheets which are fed from a manual tray 35 to a photosensitive body by the tenkey 34b of an operating panel 34 and whose both surfaces have the transfer of a developed image is set as the set value. When the set value is one, that is, the number of sheets whose both surfaces are transferred is one, the transfer sheet whose one surface is completely transferred and which is ejected from a fixing roller is directly fed to a switch back carrying unit 61 without being stacked on the manual tray 35. Thus, the carrying path for refeeding the sheet can be shortened when both surfaces are transferred, and further, the by-pass carrying path can be eliminated.
