摘要： An image forming apparatus includes an image bearer on which an image is formed; a transfer device to form a transfer portion between the image bearer and the transfer device; a voltage application device to apply a transfer voltage to the transfer device to transfer the image from the image bearer to a transfer target at the transfer portion; an abnormality sensor to detect an abnormal level of the transfer voltage; a temperature sensor to detect an ambient temperature; and a control circuit. The control circuit controls the voltage application device to continue applying the transfer voltage irrespective of whether the abnormality sensor has detected the abnormal level of the transfer voltage when a detection temperature of the temperature sensor is below a predetermined temperature.

摘要： A fixing device includes a fixing unit, a cleaning unit, and a controller. The fixing unit includes a pair of nipping members and a heat source that heats at least one of the pair of nipping members. The cleaning unit includes a cleaning web wound on a supply core to be supplied from the supply core and taken up on a take-up core, and a pressing roller that is pressed against one of the pair of nipping members. The controller causes the take-up core to rotate in such a manner that, when a leading portion of the cleaning web extending up to 2% of an overall length of the cleaning web from a leading end of the cleaning web is fed, a length of the cleaning web to be fed in one feeding is 10-30% larger than when a subsequent portion of the cleaning web is fed.

摘要： 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： A control method of an image forming apparatus including a fixing rotator includes transiting the image forming apparatus to a standby mode; detecting a temperature of the fixing rotator when the image forming apparatus is in the standby mode; 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; detecting at least one of an electric voltage, an electric current, and an electric power input to the image forming apparatus when the image forming apparatus is in the standby mode; 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; and issuing a notification that urges a recovery operation of the image forming apparatus.
