摘要： A toner density is calculated from outputs of light-receiving elements based on a difference between a reflection property of a supporting member and a reflection property of a toner pattern. Light-emitting elements aligned in one direction that is inclined to a sub-direction emit a detection light in such a manner that a distance between adjacent spots falling on the supporting member in a second direction is equal to or smaller than a width of the toner pattern in the second direction. The light-receiving elements receive a reflected light reflected from the supporting member and/or the toner pattern. The light-receiving elements are aligned, opposed to the supporting member, in a one direction corresponding to the light-emitting elements.

摘要： An image forming apparatus includes plural toner adhered amount detectors that detect an amount of toner particles adhered to the toner image on the image bearer and an image density controller to form a gradation pattern by sequentially arranging plural toner patches in the sub-scanning direction on the image bearer from the least toner adhered amount patch. These toner patches bear a different amount of toner particles from each other. The plural toner patches are detected by the plural toner adhered amount detectors, and the image density controller adjusts an image formation condition for the image formation device based on detection values thereof. These toner adhered amount detectors are symmetrically aligned in a main scanning direction above the image bearer. The image density controller forms the plural toner patches being staggered at different positions on the image bearer, facing these toner adhered amount detectors, respectively.

摘要： An image forming apparatus includes a process unit arranged in the vicinity of the circumference of each photosensitive member and the process unit is configured to act on the photosensitive member in forming a toner image thereon. The image forming apparatus detects a time period since a laser beam emission unit emits a laser beam to the photosensitive member to form an electrostatic latent image for detection until the formed electrostatic latent image for detection or a toner image based on the electrostatic latent image for detection reaches the process unit, and performs color misregistration correction control based on the result of detection. In this case, a control unit at least decreases the light amount of a pre-exposure LED when the electrostatic latent image for detection passes through a position facing the pre-exposure LED.

摘要： A system of measuring the bare belt signature of a surface that does not require the use of extra print jobs, or extra belt cycles, during the printing of the actual print job. Instead, the inter-document zone and other “toner-free” areas within the test job itself are used to extract an estimate of the bare belt signature. More specifically, prior knowledge of the job content and of the location of the area between image pitches is used to identify areas of the belt that should be toner-free. These areas are then treated as “bare belt” segments, and the sensor signal for these areas are extracted, aligned according to their spatial location along the belt, and then averaged to produce a final estimate of the bare belt signature.

摘要： In an image forming apparatus, a control portion forms a restoring toner image (restoring toner band) at a position, in which the refreshing toner image overlaps with a control image with respect to a longitudinal direction of a secondary transfer roller, during post-rotation after image formation in an image forming job is completed. The restoring toner band is formed in a length corresponding to 3 full circumferences of the secondary transfer roller for one-sheet image forming job, 2 full circumferences of the secondary transfer roller for 5-sheet image forming job, and one full circumference of the secondary transfer roller for 10-sheet image forming job. In the case of an image forming job on 50 sheets or more, a lowering in cleaning performance of a secondary transfer member cleaning device for the secondary transfer roller is not caused to occur, so that the restoring toner band is not formed.
