Inventor: SHINAGAWA KAZUTAKA
IPC: G03G15/08
Filed: 2019-02-28
Abstract: To solve the problem that for high-saturation printing, a peripheral speed ratio of a developing roller to a photosensitive drum is made higher as compared with normal printing so as to increase a toner supply amount and also raise a bias, so a toner cartridge may have a shorter lifetime and toner may deteriorate with time to cause toner to stay between the photosensitive drum and the developing roller, and if the toner stays, a striped image may be formed when a large-area dark image is printed.SOLUTION: In a state in which a mode of increasing an amount of toner supplied to an image carrier by making a rotating speed of a developing unit faster than a rotating speed of an image carrier is set, a developing bias applied to the developing unit is lowered if it is determined that the remaining amount of toner is equal to or less than a threshold.SELECTED DRAWING: Figure 8

Title: Treatment method of molten iron desulfurization slag
Inventor: NAKAI YOSHIE
IPC: B09B3/00
Filed: 2019-03-25
Abstract: To provide a method for treating molten iron desulfurization slag, by which elution of fluorine and selenium from the desulfurization slag can be suppressed so that an elution amount satisfies an environmental standard.SOLUTION: Provided is a method for treating desulfurization slag having a free lime content of 50% by mass or less, which is generated by a molten iron desulfurization treatment using a lime-based desulfurization agent. This treatment method has a sprinkling step for sprinkling water of 20 vol% or more of the slag amount to the desulfurization slag and an oxidation step for oxidizing the desulfurization slag before or/and after the sprinkling step. Fluorine is easily eluted into water in desulfurization slag having a small amount of free lime content. By sprinkling water to the slag in a predetermined condition, fluorine in the slag is dissolved and removed in the sprinkled water to reduce the amount of fluorine eluted in the slag after the treatment. Further, when the desulfurization slag is subjected to an oxidation step (further, a sprinkling step), free lime in the desulfurization slag is carbonated, and selenium is confined in the calcium carbonate in the course of the carbonation. As a result, the elution amount of selenium in the desulfurized slag can be reduced after the treatment.SELECTED DRAWING: Figure 2
