摘要： PROBLEM TO BE SOLVED: To overcome the problem that, in some cases, it is difficult to correct displacement of a toner image of each color in accordance with actual use conditions. SOLUTION: A color image forming apparatus detects displacement of images of multiple colors and controls the displacement so as to be corrected. The apparatus comprises an instruction means 36 for freely instructing the correction when a user wants to perform the correction, and a correction control means 35 for performing the control by the instruction from the instruction means 36.

摘要： PROBLEM TO BE SOLVED: To excellently form an image by completely removing toner left after transfer on a secondary image carrier in a simultaneous double-sided image forming apparatus. SOLUTION: The secondary image carrier 30 includes a secondary cleaning means 35 which has: a release agent solid body 61 obtained by solidifying a release agent 60; a brush roller (coating member) 62 applying the release agent 60 to a coating position Z on the secondary image carrier 30; and a cleaning member 63 removing the toner left after transfer on the secondary image carrier 30. By rotating the brush roller 62 with a rotary shaft 62A as a center while pressing the tip ends of the bristles 62B of the brush roller 62 against the release agent solid body 61, the release agent 60 is applied to the coating position Z while shaving the surface of the release agent solid body 61. Thereafter, the cleaning member 63 removes the toner left after transfer by cleaning at a cleaning position Y. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To supply an electrophotographic toner so excellent in durability as to ensure less carrier spent and satisfactory image density even after long-term use. SOLUTION: The electrophotographic toner contains at least a binder resin, a colorant, a release agent and inorganic fine particles. The toner is mixed with a carrier comprising magnetic particles to obtain a two-component developer for electrostatic image development having a toner concentration of 8 wt.%. The charge quantity distribution of the toner in the initial developer is determined by an increment method with a blow off device in an environment at 23°C and 55% RH and a charge quantity distribution function chart is obtained using Poisson's function. In the diagram, a peak is present in a range of 20-40 μC/g in absolute value and a total of distribution function values of ≤14 μC/g is ≤0.8 (mg/10 g). At least titania is contained as the inorganic fine particles and a rate of free titania released from the toner base determined by a ultrasonic vibration method is 5-22%.

摘要： PROBLEM TO BE SOLVED: To provide a charging device which can prevent the hazard of an image carrier by emitting electrons at a level where discharge products are never generated and reduce the degradation in an electron-emitting material itself, a process cartridge provided with the charging device, and an image forming apparatus provided with the charging device or the process cartridge. SOLUTION: An electron emitting element 1 is configured in such a manner that a sp3-bonded 5H-BN material thin film 102 is formed by irradiating an electrode 101 with a mixed gas plasma (diborane: boron hydride B 2 H 6 , hydrogen, ammonia, and argon) and simultaneously a defocused (some focused) ultraviolet excimer laser (λ:193 nm, f:1030 Hz). The image carrier is electrostatically charged by applying a voltage to the sp3 bonded 5H-BN material thin film 102, to emit the electrons, by using the electron emitting element 1.

摘要： PROBLEM TO BE SOLVED: To realize a low voltage driving of a light deflector by forming an arbitrary part (contact part or supporting point) on a substrate with which a plate-shaped member, which is a mirror, comes into contact when tilted and dislocated, or a corresponding contact part of the plate-shaped member, with a (hard) film having heat resistance and a small mechanical deformation, and suppressing a sticking. SOLUTION: A supporting point member 103, a contact part 106 and the lower layer 104a of the plate-shaped member 104 are formed by a layer consisting essentially of a high melting point metal element. The layer consisting essentially of a high melting point metal element has a high heat resistance, high Young's modulus, and hardness, shows a small mechanical deformation against the force acting by accompanying an optical deflection action (the increase in the contact area is suppressed), and the increase in sticking force is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor having high abrasion resistance which excels in electric property and hardly causes image defects such as white spots, an image forming method, an image forming device, and a process cartridge. SOLUTION: The electrophotographic photoreceptor has on its surface a hardened coating composition obtained by the radical polymerization of at least the component A. In the component A, a radical polymerizable monomer has two radical polymerizable groups and substituted amino groups including no radical polymerizable groups in a molecule, of which radical polymerizable groups and the most adjacent substituted amino group are linked by two or more aromatic hydrocarbon compounds without including unsaturated bond. The image forming method and the image forming device perform repetitively at least charging, image exposure, development, and transfer using the photoreceptor. The process cartridge has the photoreceptor 101, the charging means 102, the development means 104, the transfer means 106, the cleaning means 107, and the destaticizing means; and is attached to and removed from the body of the image forming device.

摘要： PROBLEM TO BE SOLVED: To provide an automatic document feeder, and an image forming device capable of preventing a discharge document from being retracted again into a conveying passage even when a document stopper claw and a paper discharge roller have the same drive source. SOLUTION: The automatic document feeder 4 comprises an abutting plate (a document stop claw) 25 which is movable between the blocking position to block a conveying path of a paper sheet bundle placed on a paper sheet placement table 5 and the open position to open the conveying path, and paper discharge rollers 22, 23 installed on the downstream side of the paper sheet conveying path. A drive source of the abutting plate and a drive source to rotate the paper discharge rollers are constituted of the same motor. The motor is driven in the direction opposite to the paper discharge direction of the paper discharge roller to return the abutting plate from the open position to the blocking position. When the abutting plate is returned to the blocking position, the paper discharge rollers are rotated in the direction opposite to the paper discharge direction, and the paper discharge rollers are rotated in the same direction as the paper discharge direction before or after that.

摘要： PROBLEM TO BE SOLVED: To provide LD control device and method which prevent an LD light emission amount from being set to a value different from a set value, and prevent LD deterioration even when timing of sampling signals is shifted. SOLUTION: When a lighting signal and a sampling signal are to be generated and output based on a synchronization detection signal input from a light receiving element, an image processing unit 12 performs control so that the sending time of the sampling signal is shorter than either one of the sending time of the LD lighting signal or the sending time of a channel switching signal, and the sending period of the sampling signal is included in the sending period of each of the sampling signal and the channel switching signal.
