摘要： A method is disclosed for producing a recycled developer from a waste developer generated by development of a water-developable flexographic printing original plate that has a photosensitive resin layer made from a photosensitive resin composition containing a water-dispersible resin. The method includes: leaving the waste developer to stand still in a tank so as to emerge and flocculate the photosensitive resin composition dispersed in the waste developer and thus form a solid-liquid mixed phase containing a resin flocculate beneath a liquid surface of the waste developer; and discharging the solid-liquid mixed phase containing the resin flocculate from an outlet formed on a side surface of the tank and obtaining, as a recycled developer, a liquid left in the tank, characterized in that a level of the waste developer in the tank at the time of starting the discharge is higher than the lowest position of an aperture of the outlet.

摘要： An image forming apparatus includes an image carrier, a cleaning unit, a development device, and a control unit. The development device includes a toner collection mechanism having a developer carrier and a filter. The control unit is capable of executing a scattered toner recovery mode at non-image forming time, in which the filter is vibrated, a potential difference is generated in the direction for the toner to move from the developer carrier to the image carrier, the developer carrier is rotated in a reverse direction to that at image forming time, and the image carrier is rotated in the same direction as that at the image forming time, so that scattered toner, which has dropped from the filter and adhered to the developer carrier, is recovered by the cleaning unit via the image carrier.

摘要： A first side frame is apart from a second side frame in a first direction. A photosensitive drum is rotatable about a drum axis extending in the first direction. The photosensitive drum is rotatably supported between the first side frame and the second side frame. A grip portion extends in the first direction. A first connector extends in a second direction perpendicular to the first direction. The first connector connects the first side frame and a first end portion of the grip portion. The second connector extends in the second direction. The second connector connects the second side frame and a second end portion of the grip portion. A scanner unit is configured to expose the photosensitive drum to light. The scanner unit is located between the photosensitive drum and the grip portion as viewed in a third direction which is perpendicular to the first and second directions.

摘要： A driving unit is controlled so that a driving state where an image bearing member is driven with a first potential difference formed between a brush member and the image bearing member at a contact portion where the image bearing member is in contact with the brush member transitions to a stopped state where the image bearing member stops being driven with a second potential difference formed, the second potential difference having an absolute value less than that of the first potential difference.

摘要： A cleaning device includes a cleaning member, a container, a feeding screw including a blade for feeding toner inside the container toward an outside of the container, and a loosening member, stretching along a rotation axis direction of the feeding screw, for loosening toner on a container wall surface provided around the feeding screw by being swung about a rotational axis along the rotation axis direction in a direction crossing the rotation axis direction, and the loosening member includes a contact portion for rotating the loosening member in a first direction with rotation of the feeding screw in contact with the blade when the feeding screw is in a predetermined phase range and includes an urging portion for imparting, to the loosening member, a force for rotating the loosening member in a second direction opposite to the first direction.

摘要： A cleaning device includes a blade and a seal member including a first portion having first, second and third surfaces and including a second portion having a fourth surface. The first surface opposes a free end surface of the blade. The second surface is connected with the first surface. The third surface is connected with the first and second surfaces and is perpendicular to the free end surface. The fourth surface is parallel to the third surface and the free end surface. A first interior corner line is formed by the free end surface and the third surface so as to be substantially parallel to a thickness direction of the blade. A second interior corner line is formed by the third surface and the fourth surface so as to be connected with said first interior corner line and be substantially parallel to a height direction of the blade.

摘要： A cleaning device includes a cleaning blade disposed in contact with a rotator, a toner collecting section disposed along the rotator and the cleaning blade and includes a groove extending in an axial direction of the rotator, a conveyor disposed in the groove, and an agitator disposed on a side of a rim of the groove. The conveyor rotates to convey the toner in a longitudinal direction of the groove. The agitator vibrates through contact with the conveyor and includes comb-tooth portions lined in a comb shape in the longitudinal direction of the groove, and bent portions, each of which is bent from an end of one of the comb-tooth portions. The comb-tooth portions contact a circumference of the conveyor to vibrate. The bent portions are lined at intervals smaller than intervals on a base side of the comb-tooth portions.
