摘要： An inkjet head may comprise an ejection port which ejects ink and an ink flow path which supplies the ink to the ejection port. The inkjet head may also comprise an ejection actuator which supplies ejection energy to the ink in the ink flow path. The ejection energy may cause the ink to be ejected from the ejection port. The inkjet head may also comprise a wall portion. The wall portion may be located at a position farther from the ejection port along the ink flow path with respect to a position at which the ejection energy is supplied. The wall portion may define an inner wall surface of the ink flow path. The wall portion may deform to decrease a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as a temperature of the ink in the ink flow path increases. The wall portion may deform to increase a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as the temperature of the ink in the ink flow path decreases.
摘要翻译：喷墨头可以包括喷射墨水的喷射口和将墨水供给到喷射口的墨水流路。喷墨头还可以包括向墨水流动路径中的墨提供喷射能量的喷射致动器。喷射能量可能导致墨从喷射口喷出。喷墨头还可以包括壁部分。相对于供给喷射能量的位置，壁部分可以位于比喷墨口更远离油墨流动路径的位置。壁部分可以限定油墨流动路径的内壁表面。当油墨流路中的油墨的温度升高时，壁部分可以变形，从而沿与油墨流动方向正交的方向减小油墨流动通道的横截面。当墨水流路中的墨水温度降低时，壁部分可以变形以增加与墨水流动方向正交的方向上的墨水流动通道的横截面。

摘要： A recording ink composition comprises pure water, a water-soluble dye, a polyvalent alcohol, and phosphoric acid. When iron is contained as an impurity in the recording ink composition, the iron and phosphoric acid form a ferric (III) phosphato complex ion represented by �Fe(HP0.sub.4)(H.sub.2 O)!.sup.+. Owing to the formation of the complex ion, the recording ink composition is prevented from discoloration which would be otherwise caused by iron ion. Further, the recording ink composition is prevented from formation and deposition of iron compounds. Therefore, the obtained ink has an excellent color tone, and the ink avoids blocking at a nozzle of a printing head or the like of an ink-jet printer.
摘要翻译：记录油墨组合物包含纯水，水溶性染料，多元醇和磷酸。当在记录油墨组合物中含有铁作为杂质时，铁和磷酸形成由[Fe（HPO 4）（H 2 O）] +表示的三价铁（III）磷酸盐络合物离子。由于形成复合离子，防止记录油墨组合物变色，否则将由铁离子引起。此外，防止记录油墨组合物形成和沉积铁化合物。因此，所得到的油墨具有优异的色调，并且墨水避免了在喷墨打印机的打印头等的喷嘴处的堵塞。

摘要： An image forming apparatus includes a rotatable drum; a charging roller for electrically charging the drum; a developing device for developing a latent image formed on the drum into a developer image; a cleaning device for removing a developer remaining on the drum after transfer; and a control device. The cleaning device includes a cleaning blade contacting the drum. The control device is capable of performing an operation for rotating the drum, in a direction identical to the rotational direction of the drum during image formation effected by rotating the drum, after a lapse, without next instruction of image formation, of a predetermined period from a stop of rotation of the drum after completing image formation. The predetermined period is longer with a larger number of sheets subjected to the image formation in an image forming job before the rotation of the image bearing member is stopped.
