摘要： The printer is capable of switching between a normal mode and an economy mode by acting on the print density and makes it possible to automatically determine the optimum print density according to the normal mode with serious consideration given to the print quality and the economy mode with serious consideration given to operating costs, thereby decreasing the print consumables. The print mechanism section 1 is controlled by a print controlling section 2 that selects either the print density in normal mode or the print density in economy mode according to the normal/economy instructions and controls the print density of said print mechanism section 1 to the selected print density.
摘要翻译：打印机能够通过作用在打印浓度上而在正常模式和经济模式之间切换，并且可以根据正常模式自动确定最佳打印浓度，同时认真考虑打印质量和经济模式，严重考虑到运营成本，从而减少打印耗材。打印机构部分1由打印控制部分2控制，打印控制部分2根据正常/经济指令选择正常模式下的打印浓度或经济模式下的打印浓度，并将打印机构部分1的打印浓度控制为所选择的印刷密度。

摘要： Image developing apparatus, for developing a latent electrostatic image, includes a container (12), for holding a supply of toner particles (D), and a developing roller (18) made of an electrically-conductive elastomeric material and supported for rotation in contact with toner particles in the container so as to entrain a layer of such particles and carry them to a location at which the roller engages a surface bearing such an image. A blade member (22) is pressed against the developing roller for regulating the thickness of the said layer, and respective bias voltages are applied to the developing roller and to the blade member for ensuring that the toner particles of the said layer are electrically charged in a desired manner and/or for preventing electrostatic adhesion of such particles to the blade member. Danger of localised damage due to electrical current flow between the blade member and the developing roller, prior to attainment of its normal speed of rotation, is reduced by delaying application of the bias voltages for a preset period of time after initiation of the said rotation. When such rotation is to be stopped, by termination of a drive signal (DS) maintaining that rotation, the application of the bias voltage to the blade member is terminated at a first instant. The drive signal is then terminated at a second instant, a predetermined short period of time after the said first instant, the application of the bias voltage to the developing roller being maintained until the said second instant, thereby to encourage separation of toner particles from the roller during that predetermined short period.

摘要： A recording apparatus of toner image transfer type, having an improved cleaning device for removing residual contaminants on the surface of a rotating recording drum after toner image transfer. The cleaning unit includes a blade of counter type engaging with downwardly moving surface of the drum, a rotatable cleaning brush disposed immediately upstream from the blade, and a housing structure shielding the blade and the rotatable fur brush. The housing is evacuated by an air pump, and external air is introduced from an opening of the housing, where the fur brush and the blade engage with the surface of the drum. Thereby, the contaminants removed by the blade and the fur brush from the surface of the drum is efficiently discharged by the aid of air flow having velocity enhanced by the above-described pneumatic structure. The air velocity is further enhanced by forming an air passage passing through the fur brush.
