摘要:
An image forming apparatus includes an image bearing member, a transfer member, a cleaning blade, an information storing member configured to store information on contact pressures of the cleaning blade to the image bearing member, an information input portion, and an executing portion configured to execute a toner supplying operation for supplying toner to the cleaning portion using a toner image formed on the image bearing member, in a period other than a period in which the toner image is formed on the image bearing member, for each predetermined number of image forming operations. On the basis of the information inputted to the input portion, the executing portion sets amounts of the toner supplied to the respective regions in the toner supplying operation.

An image forming apparatus comprising: an image forming section to form a toner image based on print data; a transfer section to transfer the toner image onto a transfer sheet; a fixing section to fix the toner image transferred onto the transfer sheet; a cleaning section to clean at least one of the image forming section, the transfer section and the fixing section; and a control section which determines an existence area of a real image in a print image based on the print data; determines a size of the transfer sheet, onto which the print image is printed; and controls the cleaning device based on determinations of the existence area of a real image in a print image based on the print data and the size of the transfer sheet.

An image forming apparatus (1) includes: an intermediate transfer belt (11) for, by rotation thereof, transferring a toner image on a surface thereof; a cleaner (82) for removing toner particles after the transfer by rotation of a cleaning brush (82) which touches the surface of the intermediate transfer belt (11) and rotated during the transfer; a current supplier (91) for supplying a cleaning current having a predetermined value (I2) to the cleaning brush (82) in accord with the transfer; and a controller (6) for controlling the intermediate transfer belt (11), cleaner (82) and current supplier (91). The controller (6) obtains a current time T1 and a previous rotation end time T2 of the cleaning brush (82), and when a time period during which the cleaning brush (82) has not rotated, which is calculated from the current time T1 and the rotation end time T2, is equal to a predetermined time period or longer, sets the cleaning current to "I1".

An end seal (100) for use in an electrophotographic image forming apparatus uses an array (150) of ridges (or grooves) (152) to urge toner inwardly so as to help prevent toner escape. The end seal works in conjunction with a cleaning blade (90). The end seal includes a blade pocket (130) for mating with the end portions of the cleaning blade and a middle portion (140) having an array of ridges thereon. The ridges thereon are angled inward to urge any toner trapped therebetween inward away from the end seals, where the toner can be directed to a waste reservoir in a normal fashion. This "snowplowing" action of the ridges helps prevent outward migration of toner, thereby minimizing toner escape. The end seal may be composed of two or more layers (110, 180) of differing materials. There may be an end seal at each end of the cleaner blade.

An image forming apparatus including an image bearing member (1); an intermediate transfer medium (5); a first cleaning device (6) for cleaning the image bearing member; a second cleaning device (13) for cleaning the intermediate transfer medium; a first lubricant applicator (9) for applying a first lubricant (8) to the image bearing member; and a second lubricant applicator (17) for applying a second lubricant to the intermediate transfer medium such that the intermediate transfer medium surface has a second static friction coefficient higher than the first static friction coefficient of the image bearing member surface.
