The optical unit forms an electrostatic latent image by applying scanning light onto the photosensitive member charged by the charger device from above at an angle. The developing device forms a toner image by developing the electrostatic latent image formed on the photosensitive member with toner. The transfer charger device transfers the toner image formed on the photosensitive member onto a transfer charger sheet. The main body accommodates the sheet feeding section at a rear section, and the optical unit in front of the feeding section, both of which are vertically arranged. The photosensitive member and the developing device are integrated into the image formation unit, which is detachably set in the main body. The toner box of the developing unit has a rear surface portion shaped to correspond to the optical unit, and a front surface portion shaped to correspond to an optical path through which the scanning light output from the optical unit is applied onto the photosensitive surface of the electrostatic latent image carrier.

An electrode plate is provided so as to cover the insulator layer, and a valve beam made of a conductive substance is located in an opposing relationship to the nozzle plate. A valve for opening and closing said nozzle is formed at a yieldable portion of the valve beam opposing to the nozzle. Upon energization of the electrode plate and the valve beam of a valve element thus produced, the valve is attracted toward the electrode plate to open or close the valve.

Process of producing a valve element

The present invention provides a printing device wherein a sublimable dyestuff contained in a dyestuff case is heated to sublime to form steam of the dyestuff into which gas is flowed in order to pressurize the dyestuff steam to form pressurized dyestuff steam. A nozzle plate having a nozzle formed therein for jetting the pressurized dyestuff steam toward a record medium is communicated in a closing up relationship with the dyestuff case, and a valve for opening and closing the nozzle is provided at a deformable portion of a valve beam. An electrode plate is provided in an opposing relationship to the valve and in an isolated relationship from the valve and the pressurized dyestuff steam. The valve is displaced by an electrostatic force caused by a difference in potential between the valve and the electrode plate to close the nozzle. By selectively opening the nozzle, the pressurized dyestuff steam at a high pressure is jetted from the nozzle to effect printing.
