Abstract: A waste toner container provided for use in an image forming apparatus includes: a body receiving, through an inlet, waste toner discharged from the image forming apparatus, and contains the waste toner; a conveyance member conveying the waste toner, which has been received through the inlet; a waste toner deposition chamber disposed downstream of the inlet in a waste toner conveyance direction such that the waste toner that has been conveyed is increasingly deposited therein, the chamber having a light-transmissive window through which amount of the deposited waste toner is optically monitorable from outside of the body; a conductive member disposed on an inner surface of the body so as to come into contact with the waste toner being conveyed; and a connection unit disposed between the conductive member and an earth member provided in the image forming apparatus to electrically connect between the conductive member and the earth member.

Abstract: In a paper feeding cassette storing stacked sheets, a rotary lever adapted to rotate vertically about a rotation fulcrum is provided with a lift-up portion for lifting up the sheets as placed in contact with a bottom of the sheets stored in the paper feeding cassette. The lift-up portion is vertically turned by the rotary lever.

Abstract: An image forming apparatus having a cleaner for cleaning a surface of a dust-proof glass disposed on a housing of a laser scanning unit for irradiating a photosensitive member with a laser modulated in accordance with image data. The cleaner is supported by a frame of the image forming apparatus body such that the cleaner is movable while keeping in contact with the dust-proof glass and such that the cleaner stays in a stand-by position while keeping out of contact with the dust-proof glass and the housing of the laser scanning unit.

Abstract: A method for producing glass fibers with centrifugal force, comprising melting raw materials for the production of glass fibers in a melting furnace, flowing-down the molten glass from a nozzle at the bottom of the furnace so as to let the molten glass fall onto grooves coated with a glass layer, the grooves being engraved around the total peripheral part of a rotary disc provided below the melting furnace and rotating at a high speed, and simultaneously discharging a combustion gas from a ring burner provided above the inner part of the rotary disc radially to the surroundings of the rotary disc so as to control and maintain the grooves to a prescribed temperature; and an apparatus therefor. The molten glass falling onto the grooves is elongated fibrously by radially spouting the molten glass to the surroundings of the rotary disc with the aid of centrifugal effect due to the rotation of the disc, and thus the production of glass fibers can be done satisfactorily.
