PURPOSE:To prevent the ignition and fire spread of brush hair by the abnormal current flowing to the pinhole, etc., of an electrostatic latent image carrying member by constituting the brush hair of the electrifying brush of an image forming device with resin fibers subjected to a flame-retardance treatment. CONSTITUTION:This electrifying brush is formed by cutting a pile fabric, which is formed by bundling 100 pieces of 6-denier rayon fibers 1 contg. a conductive carbon as one bundle and W weaving these fibers to the warp of a base fabric 2, to form a brush part 10, subjecting such brush part to the flame-retardance treatment, then coating the back surface of the base fabric 2 with a conductive adhesive to adhere the base fabric to a base plate 3 with the adhesive. The base plate 3 is made of an aluminum plate. This electrifying brush is used by bringing the brush hair and the surface of the electrostatic latent image carrying member into contact with each other under impression of an electrifying voltage thereon. As a result, even if the pinhole, etc., exist on the surface of the electrostatic latent image carrying member with which the brush hair comes into contact and an abnormal current flows into such pinhole, etc., the ignition and the fire spread are prevented as the brush hair is subjected to the flame-retardance treatment. |
