Image forming apparatus

An image forming apparatus comprising:

• two rotators contacting each other to form a nip through which a recording medium passes;
• a driver configured to drive the two rotators;
• a heating device including a heater configured to heat at least one of the two rotators;
• a blower configured to blow air to the heating device;
• a temperature detector configured to detect a temperature of at least one of the two rotators;
• a recording medium detector configured to detect whether the recording medium is in the nip;
• a cover disposed on an image forming apparatus body and configured to be openable and closable;
• an open-close detector configured to detect opening and closing of the cover;
• and
• circuitry configured to:
• detect an abnormal state and stop heat generation of the heater in response to detection of the abnormal state;
• determine whether the cover is closed based on a result detected by the open-close detector, control the blower to blow air to the heating device in response to determining that the cover is closed;
• determine whether the recording medium is in the nip based on a result detected by the recording medium detector;
• control the driver to rotate the two rotators in response to determining that the cover is closed and determining that no recording medium is in the nip;
• determine whether a temperature detected by the temperature detector is equal to or lower than a predetermined temperature threshold value before the open-close detector detects that the cover is opened;
• and
• control the blower to decrease an air volume blown by the blower in response to determining that the temperature detected by the temperature detector is equal to or lower than the predetermined temperature threshold value.
