A sawing wire (100,110,120,130) with abrasive particles (20) is presented wherein the particles (20) are partly embedded in said a metallic core (14) and partly in said an organic binder layer (30). The advantage of the wire (100,110,120,130) is that the application of a metallic binder layer (30) can be avoided. Metallic binder layers add to the cost of a fixed abrasive sawing wire and in many cases pose health and safety problems which can be avoided by the use of an organic binder layer. Moreover the advantages of a good fixture of the abrasive particles in the metallic wire are maintained. Different embodiments are presented with different degrees of embedment into the metal wire.

A printing apparatus is provided. The printing apparatus forms a dot in a desired position of a printing sheet by ejecting an ink droplet from a nozzle. A static electricity eliminating mechanism eliminates static electricity generated on the printing sheet by a conductive portion that is arranged in a position to which the ink droplet is ejected from the nozzle or an upstream side of such position on a path through which the printing sheet passes. The conductive portion is formed in at least one of a sheet feed roller and an idle roller that carry the printing sheet. The sheet feed roller or the idle roller is formed by coating a predetermined insulating coating on a surface of a conductive rod-shaped member. The conductive portion is formed by stripping off a part of the coating on the sheet feed roller or the idle roller.

A constant current output is applied to a backup roller or a secondary transfer member, and a cleaning bias is controlled according to a measurement obtained by monitoring a voltage generated at that time. Cleaning biases of a plus polarity and a minus polarity are alternately applied to the backup roller to recover the toner adhered on the secondary transfer member to an intermediate transfer belt. The cleaning bias is controlled according to the combined resistance of a secondary transfer section which is varied with not only the environment of an image forming apparatus, but also the condition of use and various factors to recover the toner adhered to the secondary transfer member to the intermediate transfer belt without fail, thereby preventing smudges on the back of a sheet of paper or smudges on images.
