摘要： A fixing device includes a fixing member; a heater to heat the fixing member; a nip forming member to contact the fixing member; and a pressure member, disposed opposite the nip forming member to press against the fixing member to form a fixing nip portion together with the nip forming member. The fixing device applies heat and pressure to fix an image transferred to a recording sheet when the recording sheet passes through the fixing nip. The nip forming member includes a first and second planar portions disposed at an upstream end and a downstream end, respectively, of the fixing nip portion, and the first planar portion and the second planar portion are continuous with a curved portion of the nip forming member. A guide member guides the recording sheet to bend in a direction opposite a back curl of the recording sheet generated in the fixing nip portion.

摘要： A development device is operable in multiple different speed modes and includes a developer bearer to carry developer, a developer regulator to adjust an amount of developer carried on the developer bearer, and multiple developer conveyance members disposed facing the developer bearer to transport developer in a longitudinal direction to circulate developer inside the development device. The multiple developer conveyance members including a first developer conveyance member to supply developer to the developer bearer and a second developer conveyance member to transport developer collected from the developer bearer. The development device executes developer amount balance adjustment in which a driving velocity of at least the multiple developer conveyance members is increased from a driving velocity in a lower-speed mode for a predetermined period after image development in the lower speed mode is completed and before image development in a higher speed mode is started.

摘要翻译： 显影装置可以多种不同的速度模式操作，并且包括用于承载显影剂的显影剂载体，显影剂调节器，用于调节显影剂载体承载的显影剂的量，以及面向显影剂载体设置的多个显影剂传送构件，以纵向传送显影剂 使显影剂在显影装置内循环的方向。 多个显影剂传送构件包括用于向显影剂载体提供显影剂的第一显影剂传送构件和用于传送从显影剂载体收集的显影剂的第二显影剂传送构件。 显影装置执行显影剂量平衡调整，其中至少多个显影剂输送构件的驱动速度在低速模式下的图像显影完成之后的预定时间段内从低速模式的驱动速度增加，并且在图像之前 开始以较高速度模式开发。
