摘要： PROBLEM TO BE SOLVED: To provide an electrifying device capable of uniformly electrifying a photoreceptor by preventing toner from flowing into the electrifying device and adhering to a corona electrode, and an image forming apparatus. SOLUTION: The electrifying device 5 includes: the corona electrode 53 which electrifies the surface of a photoreceptor drum 3 by corona discharge; a first power source which applies voltage to the corona electrode 53; a shielding case 51 whose one surface is made open, which has an aperture part 56 on its side surface and inside which the corona electrode 53 is housed; a grid electrode 54 with which the surface made open is covered and which controls potential by electrification on the surface of the photoreceptor drum 3; and a second power source which applies voltage to the grid electrode 54. By making an air current flow into the shielding case 51 also from the aperture part 56, sucking of the toner is restrained in comparison with a case where the air current flows into the shielding case 51 only from an open surface, because the aperture part 56 is separated from the surface of the photoreceptor drum 3 further than the open surface of the shielding case 51.

摘要： PROBLEM TO BE SOLVED: To surely peel the paper from a transfer belt by arranging a means peeling paper to the transfer belt on the downstream side of a transfer nip area. SOLUTION: In this image forming apparatus conveying the paper between a photoreceptor drum 3 and the transfer belt 103 to transfer a toner image formed on the surface of the photoreceptor drum 3 to the paper, a peeling roller 111 is arranged on the downstream side of a transfer roller 105 pressing the transfer belt 103 to the photoreceptor drum 3, and an angle difference between the conveying direction of the transfer belt 103 from the contact part 104 between the photoreceptor drum 3 and the transfer belt 3 to the peeling roller 111 and the conveying direction from the peeling roller 111 to the transfer belt 103 on the downstream side is set to be ≤19 degrees.

摘要： It is an object to provide a fluid machine, which is simple in structure and in which lubricating oil containing smaller amount of the working fluid is supplied to sliding portions of an expansion device. The fluid machine has the expansion device for generating a driving force by expansion of the working fluid, which contains the lubricating oil and is heated to a gas phase condition. The fluid machine further has an electric power generating device driven by the driving force of the expansion device and generating electric power. An oil pooling portion is formed in a fluid passage, through which the working fluid discharged from the expansion device flows, such that the lubricating oil contained in the working fluid is brought into contact with at least one of sliding portions of the expansion device and the electric power generating device. And a heating unit is provided to heat the working fluid in the oil pooling portion.
