    摘要： An electrophotographic image forming apparatus is disclosed which is provided within a cleaning device with a rotative conveying member for conveying a residual toner after removal thereof from a photoreceptor up to an inlet of a toner dropping path while rotating. Within the toner dropping path is disposed a toner bridge preventing member for preventing the formation of a toner bridge in the same path. The toner bridge preventing member is driven by the rotative conveying member so as to reciprocate substantially in parallel with the toner dropping direction.

    摘要： An image transferring device incorporated in a color image recorder has a belt made of a dielectric material and movable while sequentially contacting a plurality of photoconductive elements at successive image transfer positions. Toner images formed on the photoconductive elements are sequentially transferred to the belt or a recording medium one above another by transfer chargers. Conductive members are located to face opposite surfaces of the belt and fully spaced apart from the latter by a predetermined distance, and each has an insulating member on the surface thereof that faces the belt. The conductive members are located between a position immediately succeeding the image transfer position on the most upstreamside and the position where the recording medium leaves the belt. A belt pressing member and a transfer charge limiting member are disposed in a position immediately preceding any one of the image transfer positions with respect to an intended direction of movement of the belt. The belt pressing member urges the belt against associated one of the photoconductive elements. The transfer charge limiting member prevents the charge from associated one of the transfer charges from reaching the zone upstream of the above-mentioned immediately preceding position.

    摘要： In an image forming apparatus having an endless transferring and conveying device for conveying a recording medium and electrostatically transferring a toner image from an image carrier to the medium, the mechanical operation of an image forming section is interrupted throughout the duration of preselected image processing executed by image processing means. As a result, the amount of toner to reach a cleaning section assigned to the endless transferring and conveying means is reduced. This frees the recording medium from contamination ascribable to defective cleaning and thereby insures attractive images.
