摘要： A toner supply device including a hopper for containing the toner; a toner supply roller rotatably disposed below the hopper so as to fill an opening formed in a lower section of the hopper; a charging blade which is disposed so as to be in close contact under pressure with the toner supply roller to electrically charge the toner which is transported on the toner supply roller; a toner scraping mechanism having a toner scraping blade arranged at a position located downstream to the charging blade with respect to a rotational direction of the toner supply; a sensor for detecting the toner density; and a control unit for controlling the toner scraping mechanism depending on signals from the sensor so as to make the toner scraping blade move to one of a first position at which it comes in close contact under pressure with the toner supply roller and a second position at which the blade stands apart from the toner supply roller.When the toner supply roller is driven, a charged toner layer is formed on the peripheral surface of the roller by the charging blade. And the toner scraping blade is positioned at the first position by the control unit in the case of a low density of the toner, so that the charged toner layer thereon may be scraped off to be supplied to the developing device.

摘要： An image forming apparatus having a photosensitive unit including a film disposed thereon. The film wears over time causing its thickness to decrease, which causes non-uniformity in line image data produced by the apparatus. The invention counteracts changes in the film thickness by adjusting the intensity of the edges of the image in response to the amount of wear the apparatus has undergone. The amount of wear can be gauged by detecting the number of rotations made by the photosensitive unit or the number of sheets processed by the photosensitive unit. The invention has the particular advantage of ensuring consistency in the thickness of line images. A method for controlling exposure is also described.

摘要： An image forming apparatus includes a fog controller to control a fogging level of a toner image carrier by adjusting a fog control parameter on the basis of the fogging level detected by a fogging level detection section and the target fogging level stored in a memory section. While varying a value of the fog control parameter, the fog controller makes a detection pattern forming section to form a series of detection patterns between toner images for each page on the toner image carrier, makes the fogging level detection section to detect each of fogging levels of the series of detection patterns, determines a target fog control parameter value on the basis of each fogging level of the series of detection patterns detected and the target fogging level stored, and adjusts the fog control parameter on the basis of the target fog control parameter value.

摘要： A supply screw 10 and a collection screw 20 for a developing device equip with screw blades having different forms at particular sections so as to make conveying force of developer different depending on sections. Screw blades for big conveying force are attached within sections where developer distribution is dense while screw blades for small conveying force are attached within sections where developer distribution is sparse. In other words, conveying force is made to be greater at sparse-distribution section while smaller at dense-distribution section. Developer delivery is also promoted by providing different conveying force area within carry-up area where developer is carried up from a supply screw 10 to a collection screw 20 or vice versa. By making conveying force of each section different, developer is uniformly delivered to a developing roll 87 whether in width direction or in axial direction. Furthermore, developer circulation in a developing device becomes smooth.

摘要： An image forming apparatus includes: a moving speed ratio change section which changes a circumferential speed ratio between a surface of a developer bearing member and a surface of an image carrier; and a memory section which stores a target value of fog toner. After the circumferential speed ratio has been changed by the moving speed ratio change section, a controller determines a fog control parameter based on comparing the value detected by the fog toner detection section with the target value stored in the memory section. After then, and the controller controls the moving speed ratio change section to return the circumferential speed ratio to the circumferential speed ratio prior to the change.
