CONVEYANCE GUIDE DEVICE AND IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To provide a conveyance guide device able to prevent image disturbance when a recording material is conveyed from a transfer part to a fixing part, by restraining surface potential increase of a conveyance guide member, which results from paper passage.SOLUTION: The conveyance guide device 30 provided in an image forming apparatus for forming an image by fixing a toner image, transferred to a recording material by the transfer section, by use of the fixing section and is provided to guide the conveyance of the recording material after the transfer of the toner image and convey the recording material to the fixing nip of the fixing section has at least one or more conveyance guide members 31, which are provided with an ultrasonic vibration generator 50 for applying ultrasonic vibration to the conveyance guide member 31, thereby reducing a frictional coefficient of the surface. The vibrating surface remarkably decreases its frictional coefficient by ultrasonically vibrating the conveyance guide member. Therefore, even when the recording material and conveyance guide member contact during the conveyance, contact pressure decreases, making it difficult to cause frictional electrification and a surface potential increase, thus enabling the prevention of image disturbance when the recording material is conveyed in a process after post-transfer to pre-fixing.
