发明名称 TRANSFER MATERIAL GUIDING MEANS AND IMAGE FORMING APPARATUS PROVIDED WITH IT
摘要 <p><P>PROBLEM TO BE SOLVED: To eliminate, with a simple constitution, the soiling of a transfer material due to the soiling of a guide member with toner by preventing the occurrence of an abnormal image in transfer due to friction between the guide member and the transfer material and also to prevent transfer bias from leaking to the guide member. <P>SOLUTION: Transfer material P which is supplied to a secondary transfer nip part T2 located between an intermediate transfer belt 5 and a secondary transfer roller 12 is guided by the guide members 15 and 16. The guide member 16 is constituted of an insulating member, and a semiconductive sheet 17 is stuck to a projected part 16b where the back side of the transfer material P is strongly rubbed. The semiconductive sheet 17 is constituted of a member whose surface resistivity is≥10<SP>3</SP>Ω/Square and≤10<SP>11</SP>Ω/Square, and the radius of curvature R of the curve P2 of the transfer material P formed by the projected part 16b is set to≤6 mm, and its angleθis set to≥30°. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p>
