Pigment composition for liquid toner

The present invention is directed to a technique on a continuous drying apparatus for porous web, which comprises a heating cylinder, an impermeable drying band impermeable to air and water, coming into contact with and supporting the surface on the side having no contact with the heating cylinder of the porous web, and a plurality of water lubricating shoe members arranged around the heating cylinder apart a desired distance from the external side of the impermeable drying band, for forming a water screen flow between them and the external surface of the impermeable drying band, whereby an effective drying of the porous web is achieved.

Continuous drying apparatus for porous web

To provide an electrophotographic printer which can satisfy regulations for exhaust gas emission easily, a printer is provided with a circulation line for taking out and returning gas generated in a casing of the printer, and a heat exchanger, for cooling the gas and for recovering solvent, is provided midway on the circulation line. The heat exchanger lowers a concentration of the gas. A detection sensor detects a temperature and humidity of the gas in the casing and a heater, provided downstream of the heat exchanger, adjusts a humidity of the gas which is then returned into the casing, upon receiving an output of the detection sensor.

Electrophotographic printer

Disclosed is a liquid toner composition, comprising an ethylene-based copolymer resin, an ethylene-based copolymer resin, an electrically insulating liquid material, and a surfactant represented by general formula given below ##STR1## where R is an alkyl group or an alkylaryl group, n, which represents ad adduct ethyleneoxide mole number, is an integer of 4 to 13, and R' is H or R(CH.sub.2 CH.sub.2 O).sub.n group.

Liquid toner composition and method of manufacturing the same

In the drying apparatus for rotary printing press for drying the ink on the printed paper which has a direct fired deodorizing apparatus (8) and a heat recovery apparatus (9) for heating the hot air circulating in a drying apparatus (1) by using the exhaust gas from the deodorizing apparatus, the drying apparatus and its control device are so adapted that a bypass line (20) is installed on the hot air circulation line to bypass the heat recovery apparatus to control the temperature of printed paper and/or the temperature of hot air blowing from nozzles (3) by adjusting the degree of opening of a bypass damper (21) disposed in the bypass line, and the burning amount of the burner for deodorization is controlled so that the deodorizing apparatus furnace temperature corresponding to the blowing hot air temperature (16) or paper temperature (17) is obtained. Further, the control device carries out the control in response to the change in printing speed. Thus, the control responsiveness can be enhanced.
