摘要： The fixing device includes a pair of rotating bodies which conveys a recording medium between a nip; a heating unit which heats at least one of the rotating bodies; and a temperature detection unit which detects a temperature of at least one of the rotating bodies. The temperature detection unit detects a temperature change until an image forming apparatus is normally operated since the heating unit starts the heating, and the temperature change is stored. It is judged that the image forming apparatus is in an abnormal state when the temperature detection unit detects a temperature change different from the temperature change in the normal operation. A temperature control unit stops passage of current through the heating unit when it is judged that the image forming apparatus is in the abnormal state.

摘要： In the present applying mechanism, a part of a guide sheet 33 bulges (arches) away from an oil application roller 16, with respect to a vertical line S passing through the center of a pipe 31. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding (bypassing) the oil application roller 16 that has a high temperature. With this, oil flowing on the guide sheet 33 is kept away from the high-temperature oil application roller 16. The present applying mechanism can include an edge 50, or gap, in the guide sheet 33 for backing-up flow of oil to before the application roller in order to ensure even distribution of the oil to the application roller. The present applying mechanism can include a narrow gap between the pipe 31 and guide sheet 33.

摘要： In one embodiment, an operation state, standby state or installation environment of an image forming apparatus is detected or determined, and details of heating control of the surface temperature of rollers of a fixing apparatus are changed in accordance with the detected or determined state or environment. For example, when the operation state is a state in which printing on a last sheet of recording paper in a print job is complete, or when the operation state is a state in which printing on recording paper is interrupted, and, in addition, when the installation environment is a low-temperature and low-humidity environment and the image forming apparatus enters the standby state, heating of the rollers is respectively controlled to prevent unexpected and inappropriate changes in the surface temperature of the rollers.

摘要： A fixing apparatus and an image forming apparatus of the present invention are arranged so that a fixing control section causes a fixing roller to additionally rotate so that the additional rotation corresponds to a driving delay time also after turning OFF an external heating roller heater when shifting from a temperature raising step in which surface temperature of the fixing roller is raised so as to be equal to a preset fixing temperature to a standby mode and when turning OFF the external heating roller heater and stopping the fixing roller. As a result, it is possible to provide a fixing apparatus and an image forming apparatus in which a surface of a fixing roller is free from deterioration or breakage caused by local heating carried out by an external heating roller.

摘要： An image forming apparatus, determining in sorting recording sheets whether or not recording sheet transport interval is shorter than a first predetermined value, sets the longest time settable as a delay time when the interval is longer than the first value. When the interval is shorter than the first value, the apparatus, determining whether or not the interval is shorter than a second predetermined value, sets the shortest delay time settable when the interval is shorter than the second value, and sets a reference delay time when the interval is longer than the second value. The apparatus prevents sheet jam before a sheet eject mechanism by ensuring that the mechanism returns to an initial position before the front end of a following sheet reaches sheet eject rollers after the rear end of a preceding sheet passes through the rollers.

摘要： An image forming apparatus transfers a toner image formed on a photoconductor drum onto a sheet-like recording member while the sheet-like recording member is transported and attracted to a transfer belt, and comprises a jam handling control unit for detecting a transport fault of the sheet-like recording member, and for stopping the transport operation when the transport fault is detected. When the transport fault is detected in a section other than a fixing section, the jam handling control unit first causes the transport operation of the fixing section, and thereafter causes the transfer belt and the transport operation on the upstream side thereof to stop, and any sheet-like recording member remaining on the transfer belt so that the transport mechanism on the upstream side thereof is transported and stopped at the position spanning between the area of the fixing section and the area of the transfer belt.

摘要： A base plate detachably supports a functional unit all the way between an exposed position where the functional unit is separated from a connector and drawn out of a housing of an image forming apparatus such that the functional unit is exposed to the exterior of the housing and an accommodated position where the functional unit is fitted in the housing and connected to the connector. A biasing member biases a threaded shaft of an operating device through the base plate such that a far end of the threaded shaft is directed toward a threaded hole formed in the bottom of the functional unit. The operating device is hidden inside the housing of the apparatus when the base plate is set to the accommodated position.
