PURPOSE:To prevent irregular color and moire from occurring at the transfer of a color of a recording sheet and to improve the quality of an image by altering ink holding pore arranging angles in at least two ink conveying drums of image forming units. CONSTITUTION:Many ink holding pores 12 of cup-shaped section are formed on the surface of an ink conveying drum 10, and a blade and an ion flow write head 20 are arranged along the rotating direction of the drum 10 on the periphery. In the drum 10, pitches between the holes 12 of first color are arranged regularly in a latticelike manner, and the pitch of the holes 12 is set to the pitch L of an ion flow flux 4 or one divided by several of it. The holes 12 of the second color are arranged in a latticelike state having an angle of approx. 45 deg. with respect to the holes 12 of the first color. The holes 12 of each drum 10 are positively altered in a noncoincident range at an arbitrary arranging angle such as altering the arranging angle at each 15 deg. or 30 deg.. |
