摘要： PURPOSE:To effectively separate and remove the toners electrified to the polarity reverse from the polarity of the toners to be used from the inside of a developer without using devices, such as separating roller and high-voltage power source. CONSTITUTION:The toners 8 having a main electrification polarity are stuck to the recording body part (recording region (a) relating to transfer) desired to be stuck with the toners according to image information and the reverse polarity toners 13 of the polarity opposite from the polarity of the main electrification polarity are stuck to the recording body part (unrecording region (b) not relating to transfer) desired not to be stuck with the toners. Thus, the unnecessary toners 13 electrified to the polarity reverse from the polarity of the toners 8 to be used are removed without using a special additive device provided with a separating function, such as separating roller. The conventional developing devices are usable as they are simply by adding an exposing signal for the unrecorded region to the image information.

摘要： PROBLEM TO BE SOLVED: To reduce the size and the cost of a printer device, and to enable printing with an excellent quality and high reliability by providing at least an auxiliary charging means capable of controlling a charge quantity of the two component developer on a magnetic roll. SOLUTION: The two component developer 4 is stuck to the surface of the magnetic roller 3, and transport-development is performed by rotation of the magnetic roll 3. The toner consumed by development is replenished from the toner feeding part 5, after the layer thickness is controlled by the toner layer thickness controlling plate 8, by rotation of the foamed elastic roll 7 placed on an opening part of the toner feeding part 5, and held in contact with the two component developer 4 stuck on the magnet roll 3. At this time, the toner charge quantity is stabilized by applying a voltage from a variable voltage feeding source 11 to the auxiliary charging roller 10, and holding in contact with the two component developer. The voltage of the variable voltage feeding source 11 is provided with a specified width, based on the charge property of the two component developer 4.

摘要： PURPOSE: To shorten the time required for recovering developer by interrupting the developer at a prescribed time before a developing action is finished and continuing the developing action while the developer in a developer bank is consumed after it is interrupted. CONSTITUTION: When the developing action is not executed, a developing shutter 6 is closed. The shutter 6 is opened before the developing action is started and the developer 2 is attached to a developing magnet roll 10 provided before a doctor blade 8. Thereafter, the roll 10 and a recovery magnet roll 11 are rotated so as to start the developing action. When the developing action is finished, the shutter 6 is closed before the developing action is finished and the developing action is continued while the developer 2 at the back part of the blade 8 is consumed so that it is exhausted immediately after the developing action is finished. Therefore, the opening and closing time of the shutter 6 and an aperture state must be suitably set. In such a case, the closing time of the shutter 6 depends on the quantity of the developer 2 left in the developer bank 9 and it is emprically set before the developing action is finished.
