摘要：
An image fiber includes an image fiber body having a twisted portion which is formed by heating, softening, and twisting a portion of the image fiber body. The rate of twist in the twisted portion is made to be constant. Moreover, the rate of twist may preferably be set in a range from 3.6°/mm to 3600°/mm. In addition, the rate of twist at the beginning portion of the twisted portion and the rate of twist at the end portion of the twisted portion may preferably be set in a range from 3.6°/mm to 360°/mm. The twisted portion may be provided with a protective element.
