<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus which can surely prevent inside missing on not only ordinary paper but also material paper such as a postcard and an envelope. <P>SOLUTION: The image forming apparatus is constituted so that an image forming section 30M for magenta, an image forming section 30C for cyan, an image forming section 30Y for yellow and an image forming section 30B for black are arranged in tandem inside a housing 2 of a printer 1 along a recording medium conveying belt 8. When a recording medium is the material paper, linear speed difference between a photoreceptor drum 4 for black toner and the recording medium conveying belt 8 is made larger than that when the recording medium is the ordinary paper. As for a photoreceptor drum 4 for color toner, when linear speed difference is made larger than that at ordinary paper mode, the linear speed difference of the photoreceptor drum 4 for black toner is made larger than linear speed difference of the photoreceptor drum 4 for collar toner. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
