摘要： A toner supply device including a hopper for containing the toner; a toner supply roller rotatably disposed below the hopper so as to fill an opening formed in a lower section of the hopper; a charging blade which is disposed so as to be in close contact under pressure with the toner supply roller to electrically charge the toner which is transported on the toner supply roller; a toner scraping mechanism having a toner scraping blade arranged at a position located downstream to the charging blade with respect to a rotational direction of the toner supply; a sensor for detecting the toner density; and a control unit for controlling the toner scraping mechanism depending on signals from the sensor so as to make the toner scraping blade move to one of a first position at which it comes in close contact under pressure with the toner supply roller and a second position at which the blade stands apart from the toner supply roller.When the toner supply roller is driven, a charged toner layer is formed on the peripheral surface of the roller by the charging blade. And the toner scraping blade is positioned at the first position by the control unit in the case of a low density of the toner, so that the charged toner layer thereon may be scraped off to be supplied to the developing device.

摘要： A light shutter device including a group of light shutter elements 31a, 31b 31c and 31d formed on a light shutter chip 30 made of PLZT has a construction in which an electrode gap is set wider in a element in which an electric field acts more strongly to equalize half wavelength voltages of elements almost to the same level since electric fields acting on the elements are different in strength from each other even under a prescribed voltage applied between a common electrode 32 and each of individual electrodes 33. An electrode gap of an element 31c having a weaker electric field is comparatively set narrower, whereas an electrode gap of an element 31d having a stronger electric field is set comparatively wider. Moreover, a shape of electrodes of each element are altered so as to make half wavelength voltages of elements almost equal.
