摘要： PURPOSE:To correctly detect the presence/absence of toner in an image forming device where a replaceable toner cartridge is used by providing a magnetic permeability sensor made to press-contact with the outer peripheral bottom or outside bottom of a toner storage. CONSTITUTION:A magnetic permeability sensor 29 is made to press-contact with the outer peripheral bottom or outside bottom of the toner storage 8 provided attachably to/detachably from the image forming device main body 1. When magnetic toner sufficiently remains in the toner storage 8, high permeability is detected by the permiability sensor 29, whereas when the toner is consumed in the toner storage 8 as image formation proceeds, the toner does not remain in the vicinity of the permeability sensor 29 and low permiability is detected by the permiability sensor 29. Thus, the presence/absence of the toner in the toner storage can be detected based on the output of the permiability sensor without contact with the toner itself.

摘要： PURPOSE:To uniformize the wear of a cleaning blade and prevent chattering at both end sides by making the cleaning blade longer in free length at both end sides than at the center side. CONSTITUTION:The both-end-side free length l2 of the cleaning blade 11 which scrapes untransferred toner remaining on the surface of a photosensitive body after a transfer process is made longer than the free length l1 at the center part side. The cleaning blade 11 and a blade holding member 13 are formed longer than the effective development width L1 on the photosensitive body and a cut 13a is formed at tip parts of both end sides of the blade holding member 13.
摘要翻译：目的：使清洁片的磨损均匀化，并通过使清洁刀片在两端的自由长度比中心侧更长，从而防止两端的颤动。构成：在转印处理之后擦拭残留在感光体表面上的未转印调色剂的清洁刮板11的两端侧自由长度l2比中心部分侧的自由长度l1长。清洁刀片11和刀片保持构件13形成为比感光体上的有效显影宽度L1长，并且在刀片保持构件13的两端侧的尖端处形成切口13a。

摘要： PURPOSE:To enable a retransfer toner to be supplied throughout the cross sectional area of a photoconductor and to enable the effects of cleaning the surface of the photoconductor to be prevented from deteriorating owing to preference for some particular copy size. CONSTITUTION:In a cleaner-in developing type cleaning device in which toner collected from the surface of a photoconductor A by a cleaning blade 1 is retransferred to the surface of the photoconductor A so as to enhance cleaning effects, a paddle 6, which is provided to carry toner accumulated in the lower portion C of the front side of a housing 4 to the back side B, is provided with means for transferring a wobble 9, etc., along its axis.

摘要： PURPOSE:To surely prevent different color toner from being mixed by providing a control means which forms a high potential part and attracting electrostatically and removing toner present in a magnetic brush in a development area by the high potential part when development is not performed. CONSTITUTION:When an original placing table 1 finishes moving, a photosensor 50 detects the reflection part 51 of the original placing table 1 and its signal is inputted to a control part. The driving of the sleeve 67 and paddle 61 of a magnetic brush developing device selected according to the signal is stopped. In such a case, a photosensitive drum 2, an electrostatic charger 3, and an interimage lamp 5 are driven continuously. Then the high potential part is formed on the surface of the photosensitive drum 2 by the electrifier and interimage lamp 5, so the toner in the magnetic brush remaining on a developing roller 62 is attracted electrostatically by the high potential part and removed. Consequently, no different color toner is transferred onto an electrostatic latent image carrier where a toner image is formed by another magnetic brush developing device and the color mixing of toner is surely precluded.

摘要： PROBLEM TO BE SOLVED: To use an intermediate transfer belt for a long time by preventing or reducing trouble caused by sticking matter remaining without being removed by a cleaning device used to remove untransferred toner, which remains without being transferred to a recording sheet, from an intermediate transfer belt.
SOLUTION: The intermediate transfer belt 30 is rotated while an abrading web 220 is wound. Thereby the surface of the intermediate transfer belt 30 is refreshed while abraded by the abrasive web 220. This removes sticking matter remaining without being transferred by the intermediate transfer belt cleaning device 40.

摘要： PURPOSE:To exactly prevent the color mixture of a different color toner by providing a toner eliminating part for eliminating a toner existing in a magnetic brush of at least a developing area at the time of nondevelopment, on a developing roller. CONSTITUTION:In a development supply part 6 of a selected magnetic brush developing device 10, a black developer 3 is supplied to a developing roller 12 and a magnetic brush 16 is formed. On the other hand, this magnetic brush 16 is carried to a developing area 4 by an action of carrying poles N1-N3 and S4, slide-rubs against the surface of a photosensitive drum 2 and an electrostatic latent image is converted to a developed image. Subsequently, a rotation of a sleeve 18 is stopped through a control part. Immediately before the rotation of the sleeve 18 stops, a bias roller 13 starts to turn, and also, from a power source V1, a DC bias is applied, and a toner in the magnetic brush 16, remaining on the developing roller 12 is absorbed electrostatically by the roller 13 and eliminated. The toner which has been eliminated by the roller 13 is peeled off by a blade 17 for abutting on the roller 13 and collected into a housing 11.

摘要： PURPOSE:To prevent skew from producing by arranging ribs protrudedly on the sheet guide surface of a side guide plate when sheets are conveyed in a sheet conveying path of an image forming device and also restricting the side parts of the sheets when the sheets are conveyed in the sheet conveying path. CONSTITUTION:Sheets P fed from paper feeding trays 11 and 11a are fed from a paper feeding path corresponding to the trays to the image recording part of a device main body through a sheet conveying path 20 formed vertically. In the sheet conveying path 20, multiple ribs are arranged on the sheet guide surface of a side guide plate 30 according to the width of the sheets, and the side parts of the sheets are restricted by the ribs for conveying action. Also an elastic body 50 is arranged to press the side parts of the sheets against the ribs, and the elastic body 50 is projected from the end part of an upper guide plate 45 to the position for conveying by a conveying roller device.
