摘要:
A fixing device includes a pressure rotator to press against a fixing rotator to form a fixing nip therebetween, through which a recording medium is conveyed. A cleaning web cleans one of the fixing rotator and the pressure rotator. A web driver displaces the cleaning web to change a contact portion of the cleaning web, which contacts the one of the fixing rotator and the pressure rotator. A controller performs a temperature maintenance and rotation control to heat and rotate the fixing rotator at a predetermined time when the fixing device is in a standby mode in which the recording medium is not conveyed through the fixing nip. The controller controls the web driver at a predetermined time to perform a standby mode cleaning control to change the contact portion of the cleaning web according to an implementation status of the temperature maintenance and rotation control.

A control method of an image forming apparatus including a fixing device including a fixing rotator includes starting warming up the fixing device; detecting at least one of an electric voltage, an electric current, and an electric power input to the image forming apparatus when the fixing device is warmed up; detecting a temperature of the fixing rotator when the fixing device is warmed up; determining that the image forming apparatus is in a low input state that does not satisfy a predetermined input condition based on the detected one of the electric voltage, the electric current, and the electric power; determining that the fixing rotator is in a low temperature state that does not satisfy a predetermined heating condition based on the detected temperature of the fixing rotator; and issuing a notification that urges a recovery operation of the fixing device.
摘要:
In a laminating apparatus for a ceramic green sheet according to the present invention, cutting means and laminating means are positioned on a conveying path of a carrier film conveyed by conveying means. Specifically, cutting of the ceramic green sheet and lamination of sheet pieces are carried out on a single conveying path. Consequently, the reduction of production efficiency is prevented significantly. Furthermore, the position of the cutting means and the position of the laminating means are different. Therefore, even when cut scraps are generated when the ceramic green sheet is cut by the cutting means, the cut scraps are significantly prevented from entering between layers in a green sheet laminated body.
