摘要： A method and apparatus for image forming includes a hybrid developing apparatus that supplies surly charged toner to a developing roll. The apparatus includes a developing roll that is electrically conductive at least on its surface. The image forming apparatus and the method have a constitution capable of applying an alternating current bias having a duty ratio in the range of 10 to 50% and a direct current bias superposed thereon. The developing roll is directly confronted with a latent image bearing body through an insulative toner thin layer at the nearest region of the developing roll and the latent image bearing body. An independent bias is applied to each of the developing roll and the magnetic roll, and the toner is refreshed by the varying duty ratio of the alternate current bias and the direct current bias after developing.

摘要： A recording head utilizes an AND circuit which performs logical product between inputs from signal input terminals and a warning signal output terminal which outputs a result of the AND circuit. A recording apparatus in which the recording head is installed has a control circuit which supplies a high level signal to the signal input terminals and which inputs a warning signal from the warning signal output terminal. The control circuit judges that the contact of the recording apparatus with the recording head is good if the warning signal is a high level, or judges that the contact is poor if it is not so.

摘要： An ink cartridge for ink jet use is provided with an aperture for filling in the cartridge with ink. The circumference of the aperture and a part of a plug pressed in the aperture are fused and welded to be formed integrally to airtightly close the aperture, and obtain an integrated structure without any interface. Hence, it is made possible to reliably prevent ink from leaking therefrom, even if some scratches and cracks are present on both of them. This contributes to eliminating inspection steps to find ink leakage in the course of manufacture, and also, contributes to improving the yield of production. As a result, a significant reduction of costs is possible, while enhancing the reliability of the ink cartridge.

摘要： An ink jet head has a first member having a plurality of energy generating elements for generating energy necessary for ejecting ink, a second member having a plurality of grooves separated by land portions, the grooves constituting an array of ink channels leading to an array of ink ejecting openings and the land portions constituting ink channel walls separating the ink channels, and a pressing member for pressing the first member and the second member to each other, thereby joining these members so that the ink channels are formed by cooperation between the first member and grooves in said second member. The height of ink channel walls is varied such that it is smaller at both end regions of the array of ink channels than at the central regions of the array of ink channels. Close and tight contact between the first member and the second member is attained in the central region of the ink channel array where the ink channels actually perform ejection of ink, so that ink can be discharged accurately without any crosstalk between adjacent ink channels, thus ensuring high quality printing.
