摘要： A toner near empty discriminating unit discriminates a near empty indicating that the toner approaches an empty state on the basis of a detection value of a toner sensor. When the toner near empty is determined, a toner supply amount calculating unit calculates a toner supply amount (w) per time as w = W/X from the number (X) of toner supplying times of a toner supply counter and a specified toner filling amount (W) when a toner cartridge is set. On the basis of the calculated toner supply amount (w) of one time, a correction processing unit corrects a rotational speed of a supply roller of a toner supply control unit and an operation time of the supply roller, or the number of discriminating times of the toner empty and the number of discriminating times of a replacement of an expendable item.

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.

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： A developing unit for developing an electrostatic latent image with two-component developer includes a developer holding container (66) and a toner replenishing means.
The developer holding container (66) comprises a developer storage portion (70) and a developer agitating porition (76) disposed above the developer storage portion, wherein a communicating path (84, 84') is formed between the developer agitating portion and the developer storage portion, and the communicating path is open to the developer agitating portion so that a developer overflow outlet (66h, 66h') can be formed.
The toner replenishing means replenishes a toner component to the developer agitating portion (76) and is positioned with respect thereto so that the replenished toner component can reach the developer overflow outlet (66h) after the replenished toner component has been sufficiently agitated by developer agitating means so as to be triboelectrically charged.
The developer overflow outlet (66h') is formed into a slit-shaped overflow outlet disposed adjacent to developer lifting means (86, 88, 86'), the slit-shaped overflow outlet being open on a vertical plane and extended in a horizontal direction. The developer agitating means is composed of a pair of conveyance screws (78a, 78b), and the width of the slit-shaped overflow outlet is determined so that a ratio of the width to the outer diameter of the conveyance screw can be in a range from 1/9 to 7/27.
