发明名称 IMAGE FORMING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing the occurrence of image defects in margin-less print. <P>SOLUTION: The structure of a transfer portion is switched between the margin-less print and a normal print, and further the margin-less print cannot be carried out with a structure of the transfer portion for the normal print. This is because, when the so-called margin-less print is carried out with the structure of the transfer portion for the normal print, there is a possibility that the image defect of a print image to be output is caused, or a stain on a rear surface of recording material is caused. <P>COPYRIGHT: (C)2008,JPO&INPIT
