<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus for forming a good image by securing good transfer property without any transfer failure due to void, etc., in letters and securing good magnifying property for printing. <P>SOLUTION: The image forming apparatus 1 is provided with a photoreceptor drum 32 carrying a developer image formed according to image information, a PS roller 31 conveying a recording material, a transfer unit 36 transferring a developer image on the photoreceptor drum 32 electrostaticly to the recording medium by being abutted to the photoreceptor drum 32 and a fixing roller 38c fixing the developer image transferred on the recording material onto the recording material. When the recording material conveyance velocity by the PS roller 31 is Vps, rotational peripheral velocity by a photoreceptor drum 32 is Vdr , rotational peripheral velocity by the transfer roller 103 is Vtr and recording material conveyance velocity by the fixing roller 38c is Vfu, the relation among respective velocities is Vdr<Vps<Vfu<Vtr. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
