Zusammenfassung:PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing transfer failure by suppressing the undesired charging of a transfer material caused by the charging of resist rollers. SOLUTION: The image forming apparatus includes: a transfer roller 102 rotating in contact with an image carrier 100 of a belt form; and the pair of resist rollers 22 and 23 for conveying a transfer material 104 to the area where the transfer roller 102 and the image carrier 100 of the belt form are in contact with each other. The image forming apparatus transfers a toner image, formed on the image carrier 100, to the transfer material 104 by the application of current or voltage to the transfer roller 102. Each of the resist rollers 22 and 23 is formed of an insulator, and a charge removal member 24 is disposed so as to be brought into contact with the resist rollers 22 and 23 or separated therefrom. When the transfer material 104 is in contact with the resist rollers 22 and 23, the charge removal member is separated from the rollers 22 and 23. When the transfer material 104 is not in contact with the resist rollers 22 and 23, the charge removal member 24 is brought into contact with them. COPYRIGHT: (C)2009,JPO&INPIT
