    • A fixing device includes an excitation coil, a fixing member heated by electromagnetic induction by the excitation coil, a magnetic shunt alloy member, a Curie temperature of which is higher than a target fixing temperature, a determiner that determines whether the temperature of a non-sheet passing region of the fixing member is about to reach the Curie temperature, and a power controller that controls power supplied to the excitation coil. Until the determiner determines that the Curie temperature is about to be reached, the power controller performs feedback control to provide power to the excitation coil. When the determiner determines that the Curie temperature is about to be reached, the power controller switches to fixed power control so that a difference between power supplied when the Curie temperature is about to be reached and power supplied after reaching the Curie temperature falls within an allowable range.

    • An authentication printing function is performed in a multi function peripheral (MFP). A user transmits a job from a PC to the MFP, and then performs card authentication by bringing cards close to an authentication device. Authenticated-user information is transmitted to the MFP, where the authenticated users are registered. A print job is generated, and a billing scenario is generated in which a charge is allocated among the plurality of authenticated users on the basis of a billing pattern. When the billing scenario is approved by the user, the job is executed, and the authenticated users are each billed for the charge allocated thereto on a per-page or per-set basis, in accordance with the billing scenario. Accordingly, a billing device for an image processing device which can allocate a charge among a plurality of users without the need of complicated operations is provided.
    • 在多功能外围设备(MFP)中执行认证打印功能。 用户从PC发送作业到MFP,然后通过将卡片靠近认证设备来执行卡片认证。 认证用户信息被发送到已经认证的用户注册的MFP。 生成打印作业,并且基于计费模式生成在多个认证用户中分配费用的计费方案。 当计费方案被用户批准时,根据计费情况,执行作业,并且按照每页或每个基础,为已分配给它们的费用收取经过身份验证的用户。 因此,提供了一种能够在不需要复杂操作的情况下在多个用户中分配费用的图像处理装置的计费装置。
