    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： The disclosure relates to a developing apparatus having a developing sleeve for making a latent image visible and a bucket roller for supplying developer to the developing sleeve including a plurality of buckets provided on the circumferential surface of the bucket roller at a predetermined spacing and base portions for supporting the buckets respectively.Each of the buckets are loosely provided at the base portions respectively so as to pivot with respect to the base portions. This construction effectively prevents the aggregation and accumulation of developer at the bucket portion, as well as gives sufficient flowability to the developer.
