US08112022B2 Fixing device, image forming apparatus, and image fixing method capable of stably applying oil for fixing without adhering oil to sheet 有权
固定装置，图像形成装置和图像定影方法，其能够在不将油粘附到片材上的情况下稳定地施加用于定影的油

Fixing device, image forming apparatus, and image fixing method capable of stably applying oil for fixing without adhering oil to sheet
Abstract:
In a fixing device, a controller switches a pressing member between a pressure application state to contact the pressing member against a fixing member and a pressure release state to separate the pressing member from the fixing member. The controller starts rotation of the pressing member before the pressing member contacts the fixing member in the pressure application state, when the pressing member switches from the pressure release state to the pressure application state. An oil applier includes an oil pan and an oil regulating member. The oil pan is provided under the pressing member to contain oil in which the pressing member is dipped. The oil regulating member is provided downstream from the oil pan in a direction of rotation of the pressing member to contact the pressing member to regulate an amount of oil adhering to the pressing member.
Abstract(Chinese):

在定影装置中，控制器在压力施加状态之间切换按压构件，以将压紧构件接触固定构件和压力释放状态，以将按压构件与固定构件分离。 当按压构件从压力释放状态切换到压力施加状态时，控制器在加压构件在压力施加状态下接触固定构件之前开始按压构件的旋转。 一种油涂器包括油盘和油调节件。 油底壳设置在按压部件的下面，以容纳浸入按压部件的油。 油调节部件沿着按压部件的旋转方向设置在油盘的下游，以接触按压部件，以调节附着在按压部件上的油量。
