When the toner supplier supplies toner particles to the toner carrier, the toner carrier carries toner particles to adhere to a latent image formed on the latent image carrier and has a time constant τ1 of a surface electrical potential change of the toner carrier. The surface electrical potential controller has a time constant τ2 of a surface electrical potential change of the toner carrier smaller than the time constant τ1. The toner carrier includes a plurality of electrodes aligned in parallel and electrically insulated from each other on the surface thereof, and a voltage supplier for supplying each of the plurality of electrodes with a voltage to periodically switch electrical fields therebetween, so that the toner particles form a cloud on the surface of the toner carrier while hopping.

摘要： Provided are an inkjet printing apparatus and a method of controlling an inkjet printing apparatus whereby the performing of a suction discharge operation, for air bubbles that have penetrated inside an ink supply line, can be suppressed to a minimum necessary number of times, and whereby the ink discharge volume that accompanies air bubble suction discharge operations can be kept low. The volume of an air bubble that penetrates into an ink supply line is estimated on the basis of an elapsed time since the last air bubble suction discharge operation, and in addition, the volume of an air bubble that penetrates into the ink supply line during main tank installation is predicted. The suction discharge operation (choke suction operation) for suctioning out and discharging air bubbles is conducted when the sum of these estimated volumes becomes equal to or greater than a predetermined value.

摘要： The inkjet printer in the present invention can discharge a bubble in an ink flow path while suppressing ink consumption. Ink in an ink tank is supplied to a printing head through a flow path and filter 48. Bubbles in the flow path and printing head 22 are discharged by applying a negative pressure to an ejection port of the printing head. At this time, after a first negative pressure has been applied to the ejection port with an on/off valve provided between the ink tank and the filter being closed, the on/off valve is opened to discharge the ink from the ejection port. Further, after that, a second negative pressure that prevents a bubble from passing through the filter is applied to the ejection port to discharge a bubble present more closely on the printing head side than the filter from the ejection port together with the ink.

摘要： In a cogeneration system having a first power plant connected to an AC power feed line between a power network and an electrical load and a first internal combustion engine for driving the first power plant such that exhaust heat of the first engine is supplied to a thermal load, power supply from the first power plant to the power network is interrupted by turning off a switch installed in the feed line, when outage of the power network is detected and a second power plant is operated, such that outputs of the first and second power plants are supplied to the electrical load. With this, it becomes possible to respond to a commercial power network outage for preventing reverse flow of the power output by the cogeneration system into the power network and supplying as much electric power as possible to the electrical load.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.

摘要： A development device includes an open-ended housing, a rotatable roller, an array of multiple primary electrodes, a voltage source, a sealing member, and a secondary electrode. The housing accommodates toner for application to the photoconductive surface through an end opening thereof. The roller has an outer circumferential surface to deliver the toner from within the housing to a development zone. The array of multiple primary electrodes are aligned with each other on the roller surface. The voltage source applies a periodic pulse voltage to at least a subset of the primary electrodes to generate an oscillating primary electric field. The sealing member seals clearance between the roller surface and an edge of the end opening downstream from the development zone. The secondary electrode generates a secondary electric field to force the toner from the sealing member toward the roller surface to prevent premature removal of the toner.

摘要： An apparatus for developing a latent image on a latent image carrier includes a toner carrier and multiple electrodes arranged at intervals on a surface of the toner carrier. A potential difference is formed between even-numbered electrodes and odd-numbered electrodes of the electrodes by applying a first pulse voltage to the even-numbered electrodes and a second pulse voltage to the odd-numbered electrodes so that toner on the surface of the toner carrier moves back and forth between the electrodes, where the first and second pulse voltages are in different phases, and the toner moving back and forth between the electrodes is conveyed to a position facing the latent image carrier by movement of the surface of the toner carrier and thereby caused to adhere to the latent image on the latent image carrier.
