摘要： PROBLEM TO BE SOLVED: To provide a toner bottle 20 excellent in the ability of discharging toner from an aperture part 23 and reducing the adhesion of the toner to the outer surface of the toner bottle 20 around the aperture part 23 to be smaller than in the conventional manner.
SOLUTION: The aperture part 23 is formed on one end wall of the toner bottle 20 so that its diameter may be smaller than the diameter of a cylindrical main body part. By extending a part of the inner surface of the shoulder part of an end face where the aperture part 23 is formed to the edge of the aperture part 23 from the inner surface part of the shoulder part, an extended part 85 for lifting up the toner is formed. By extending the inner surface part of the peripheral wall of a container ranging to the extended part 85 in a peripheral direction further than the edge of the aperture part 23 in the direction of the center line L of the rotation of the container, an extended part in the aperture 86 is formed. Then, the toner is smoothly discharged by lifting up the toner existing at the lower part of the cylindrical main body to the aperture part 23 by the rotation of the toner bottle in a state where the toner bottle 20 is nearly horizontally placed on the bottle holder of a toner replenishing device so that the aperture part 23 faces sideways.

摘要： PROBLEM TO BE SOLVED: To shorten a time required for fixing by stably penetrating the droplet of a fixing liquid up to the back part of unfixed toner and recording paper, and to enhance an energy saving effect.
SOLUTION: An AC voltage, whose working point is offset to the side of the reverse polarity of the unfixed toner 3 is applied from an AC power supply 13 to an electrode 6 for generating a Coulomb force sucking the droplet 11 of the electrified fixing liquid, in order to fix the unfixed toner 3 on the recording paper 2, to more easily penetrate the droplet 11 of the fixing liquid up to the inside of the unfixed toner 3 from its surface and the recording paper 2 as compared with the case in which a DC voltage is applied to the electrode 6 for generating the Coulomb force sucking the droplet 11 of the fixing liquid. Thus, the unfixed toner 3 is stably fixed on the recording paper 2.
