    • In an image forming apparatus provided with a cooling fan for cooling an original table glass, a controller measures a cooling time from the end of a previous copying operation to the start of a current copying operation. An operating condition determining section estimates a residual amount of heat energy based on the measured time and the generated amount of heat energy at the pervious copying operation. An amount of heat energy to be generated at the current image forming is added to the thus estimated residual amount of heat energy. Based on the sum of the heat energy, actual temperature-rise characteristics are calculated. The fan is driven at a rotating rate for an operating time in accordance with the thus calculated temperature-rise characteristics.
    • 在设置有用于冷却原稿台玻璃的冷却风扇的图像形成装置中,控制器测量从先前复印操作结束到当前复印操作开始的冷却时间。 操作条件确定部基于所测量的时间和所产生的热能的量来估计剩余的热能量。 在当前图像形成时将产生的热能的量加到如此估计的剩余热能量上。 基于热能的总和,计算实际的温升特性。 根据这样计算的温升特性,风扇以转速驱动运行时间。

    • An ink for ink-jet recording is provided, which makes it possible to obtain vivid recorded matters by satisfying both of the prevention of the feathering and the prevention of the bleeding even when the recording is performed on regular paper. The ink for ink-jet recording contains a self-dispersing type microparticulate coloring agent, a surfactant, and water. When the surface tension is plotted in the vertical axis, and the concentration of the surfactant is plotted in the horizontal axis, then the correlation between the surface tension and the concentration of the surfactant can be represented by a correlation curve which has one inflection point and which has two local maximum points of curvature on both sides of the inflection point one by one. Further, the ink for ink-jet recording contains the surfactant at a concentration which is higher than a concentration corresponding to the local maximum point of the curvature on the low concentration side.
    • 提供了一种用于喷墨记录的墨水,这使得即使在普通纸上进行记录的同时,也可以通过同时满足防止羽化和防止渗色两者而获得生动的记录。 用于喷墨记录的油墨包含自分散型微粒着色剂,表面活性剂和水。 当表面张力在纵轴上绘制,表面活性剂的浓度在水平轴上绘制时,表面张力与表面活性剂浓度之间的相关性可以用相关曲线表示,该相关曲线有一个拐点, 其在拐点的两侧具有两个局部最大曲率点。 此外,用于喷墨记录的油墨含有浓度高于在低浓度侧的曲率的局部最大点的浓度的表面活性剂。
