In a copying machine having a stripping pawl bearing against a photosensitive medium, a separator device comprises a pair of separator-conveyor rollers disposed immediately behind the stripping pawl adjacent one end of the photosensitive medium. The rollers are rotatable at a peripheral speed substantially equal to that of the photosensitive medium and adapted to hold therebetween a transfer medium which has been partly separated from the photosensitive medium by the stripping pawl and to guide the transfer medium away from the photosensitive medium.

An electric injection apparatus comprising a hydraulic cylinder for back pressure control. The electric injection apparatus includes rear and front supports integrally coupled to each other by a tie bar with a predetermined spacing therebetween. A heating barrel having an injection screw arranged therein is attached to the front support. Between the supports, a screw thrust member having an injection screw rotatably coupled to its front center is movably arranged so that the tie bar penetrates therethrough. Besides, the cylinder in the hydraulic cylinder is isolated from the heating barrel. This eliminates thermal effects and allows stable back pressure control in long-hour use.

The present invention provides an image forming apparatus with a first accommodating cassette for accommodating sheets, a second accommodating cassette arranged above the first accommodating cassette and adapted to accommodate sheets, an image forming device arranged above the second accommodating cassette and adapted to form an image on the sheet, a first sheet guide path for feeding the sheet from a first end of the first accommodating cassette to an image forming station, and a second sheet guide path for feeding the sheet from a second end of the second accommodating cassette and joined to the first sheet path. A curl correction device causes sheets from different cassettes to bend in the same direction.

A data transmission system has a data converter for converting character code data into dot image data, and/or vice versa. The data converter has a memory and a pattern generator and/or a character recognition apparatus to perform such conversion. The system allows data transmission in either form with a smaller number of lines to connect respective stations, and also allows direct communication between the stations.

An ozone filtering mechanism in an image forming apparatus such as office copiers, etc. and its arrangement, wherein various component elements disposed in the image forming apparatus in such a manner that a flow path for a discharge current of ozone gas generated from a corona discharger and a flow path for heat current from a heat source such as a light source, etc. may be centralized at one place, thereby enabling a single ozone filter to be disposed at this portion of the centralized flow paths for perfect ozone filtration. Presence of the heat current at the time of the ozone filtration promotes adsorption and decomposition of ozone to augment the filtering effect to the maximum possible extent.

An image forming apparatus includes an image carrier for carrying an image, and a transfer medium bearing member for bearing and conveying a transfer medium to a transfer unit of said image carrier. The transfer medium bearing member is able to bear multiple transfer media concurrently. The apparatus includes transfer device for transferring the image of the image carrier onto the transfer medium borne on the transfer medium bearing member in the transfer unit, and a plurality of transfer media capable of being borne on the transfer medium bearing member concurrently, wherein in consecutively transferring the image onto the transfer media of the number not divisible by the maximum sheet bearing number by which said transfer medium bearing member is capable of bearing the transfer media concurrently. The number of transfer media that the transfer medium bearing member concurrently bears at the n-th time where n is a natural number equal to or greater than two, is not less than the number of transfer media that it bears concurrently at the n-1-th time. In transferring the image consecutively as above, the number of sheets that the transfer medium bearing member concurrently bears at the final time is greater than the number of transfer media that the transfer medium bearing member concurrently bears at the first time.
