摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of preventing generation of transfer omission or transfer defects with a simple construction and of continuously obtaining stable images. SOLUTION: The image forming apparatus has an image carrier 1; a developing means 4 which develops an electrostatic latent image on the image carrier 1; a lubricant application means 3 which applies a lubricant onto a surface of the image carrier 1; an intermediate transfer body 56 which is disposed in contact with the image carrier 1 and to which the developed electrostatic latent image is transferred from the image carrier 1; and a cleaning means 57 which removes transfer residual toner on the surface of the intermediate transfer body 56. The image forming apparatus has a frictional resistance detection means 52a which detects frictional resistance of the surface of the intermediate transfer body 56, and controls an amount of the toner input on the intermediate transfer body 56 in a non-image section area according to the detection result from the friction coefficient detection means 52a.

摘要： PROBLEM TO BE SOLVED: To provide a compact developing device which sufficiently agitates a developer and generates an image without density unevenness. SOLUTION: The developing device includes a developing part including: a developer carrier 2 for latent image development having a fixed magnet therein; a developer supply member 3 which supplies the developer to the developer carrier 2 from below the developer carrier 2; a developer collecting means which separates the developer from the developer carrier 2 to drop the developer to the developer supply member 3 in a region where a normal magnetic flux density generated by the fixed magnet is low, after an electrostatic latent image is developed in a region where the normal magnetic flux density is high; and a regulating member 6a which is located in a collection path through which the developer is separated from the developer carrier 2 and is collected to the developer supply member 3, and regulates a path of the developer. The developer supply member 3 serves also as a first developer conveying means for conveying the developer in one of longitudinal directions of the developer carrier 2, and the regulating member 6a serves also as a second developer conveying means for conveying the developer in a direction opposite to the developer conveying direction of the first developer conveying means.

摘要： PROBLEM TO BE SOLVED: To provide a developing device in which such a defect that density irregularities occur on an output image is reduced because toner is sufficiently stirred and mixed into developer in a developer circulation path and to provide a process cartridge and an image forming apparatus. SOLUTION: The developing device includes: a first developer conveying part 53Y which supplies the developer to a developer carrier 51Y, while conveying the developer in the longitudinal direction by a first developer conveying means 55Y; and a second developer conveying part 54Y which conveys the developer sent in from the downstream side in the conveying direction of the first developer conveying part 53Y, in the longitudinal direction by second developer conveying means 56Y and 57Y, to send out the developer to the upstream side in the conveying direction of the first developer conveying part 53Y. The second developer conveying means are a plurality of screw-like rotating members 56Y and 57Y and disposed so that the position of the top of the screw part of at least one screw-like rotating member 57Y of the plurality of screw-like rotating members is deviated from the position of the top of the screw part of the other screw-like rotating member 56Y in the rotational axis direction.
