Image forming apparatus capable of properly inhibiting automatic printing

An image forming apparatus having a copying function for reading an original image and executing printing and an automatic printing function for automatically printing an image received externally, comprising:

• an operating means for setting an operation mode of the copying function;
• a first time counting means for counting a first inhibition time after the end of operation of the operating means;
• a second time counting means for counting a second inhibition time different from the first inhibition time after the end of a print operation by the copying function;
• and
• an inhibiting means for inhibiting print operation by the automatic printing function during counting either the first inhibition time or the second inhibition time.

An image forming apparatus having a copying function for reading an original image and executing printing and an automatic printing function for automatically printing an image received externally, comprising:

• an automatic document feeder unit for successively conveying original sheets in a stack set on an original tray to a read position;
• a first time counting means for counting a first inhibition time after the end of a print operation of an original set manually by the copying function;
• a second time counting means for counting a second inhibition time different from the first inhibition time after the end of a print operation of an original set by the automatic document feeder unit by the copying function;
• and
• an inhibiting means for inhibiting print operation by the automatic printing function during counting either the first inhibition time or the second inhibition time.

An image forming apparatus having an auto-clear function for automatically setting an operation mode back to an initial mode when no operation is executed for a specified time, comprising:

• an original conveying means for automatically successively conveying original sheets in a stack set on an original tray to a read position;
• and
• a changing means capable of changing an auto-clear operating time until the auto-clear effect after the end of a print operation or after the execution of last operation,
• the changing means setting the auto-clear operating time after the end of the print operation when the original is automatically set in the original read position by the original conveying means shorter than the auto-clear operating time after the end of the print operation when the original is manually set in the original read position.
