摘要： A developing device comprises a latent image carrier that carries a latent image, a toner carrier opposing the latent image carrier while carrying toner to develop the latent image, and plural electrodes arranged in a prescribed direction insulated from each other on the surface of the toner carrier to create an electric field therebetween. An alternating voltage supplying device is provided to supply n number of phases (n ≧2) of an alternating voltage to the plural electrodes, respectively. The alternating voltage changes the electric field to cause the toner to hop and form toner cloud on the surface of the toner carrier. The toner hopping is halted at a prescribed time period during the toner cloud formation.

摘要： An image forming apparatus is capable of specifying the type of an occurring abnormality to a certain extent while avoiding the increasingly complicated control that is caused when a plurality of abnormalities is detected individually according to the presence of their respective causes. A normal group data set, which is a collection of normal value combinations relating to grouped information constituted by a plurality of information of differing types, is stored in RAM or ROM serving as information storage means of a control unit. At least two or more sets of grouped information, comprising first grouped information constituted by a plurality of different types of information, and second grouped information constituted by a plurality of information in a different combination to that of the first grouped information, are obtained from the RAM, the ROM, various sensors, and an operation display unit. A CPU serving as determining means determines a Mahalanobis distance for each set of grouped information on the basis of the normal group data set and the obtained results of each set of grouped information, and uses this Mahalanobis distance to determine the presence of an abnormality according to categories.

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.
