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 for fixing an image formed on a recording material includes first and second rotary members having a nip part therebetween, a heating part that heats the first rotary member, a center portion temperature detecting unit that detects a temperature of a center portion of the first rotary member, and an end portion temperature detecting unit that detects a temperature of an end portion of the first rotary member. When recording materials each having a relatively large width consecutively pass through the nip part, a control unit controls a heating amount of a full width heating member based on the temperature detected by the center portion temperature detecting unit, and when recording materials each having a relatively small width consecutively pass through the nip part, the control unit controls the heating amount of the full width heating member based on the temperature detected by the end portion temperature detecting unit.

摘要： A fixing apparatus includes a first heat generating member that generates heat upon receiving power from a commercial power source, an electrical condenser that stores charge when charged by the commercial power source, and a second heat generating member that generates heat upon receiving power from the electrical condenser. A fixing member is heated by the first and second heat generating members and fixes an image onto a recording medium. A control device is provided to restrict the power supplied from commercial power source to the first heat generating member when the temperature of the fixing member starts increasing. The electrical condenser starts supplying power to the second heat generating member before the control device terminates restriction of the power.

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.
