Image forming apparatus, image forming method, and printing system

An image forming method implemented by an image forming apparatus that is communicable with a terminal device and that includes an interface section, a data storage section, an input section, an authentication section, and an image forming section that forms an image on a sheet,

• the image forming method comprising:
• receiving, by the interface section, of a print job that is transmitted from the terminal device and that is assigned terminal identification information identifying the terminal device;
• outputting, by the interface section, of the print job received from the terminal device to the data storage section;
• storing, by the data storage section, of the print job output from the interface section;
• receiving, by the input section, of input information that is input by a user;
• and
• in accordance with whether or not the authentication section positively authenticates the user based on the input information before a specified time elapses from the interface section receiving the print job from the terminal device, outputting, by the interface section, of the print job stored by the storage section to the image forming section or the terminal device, and deleting, by the data storage section, of the print job stored.

A printing system comprising:

• a terminal device;
• and
• an image forming apparatus communicable with the terminal device, wherein
• the image forming apparatus includes an interface section, a data storage section, an input section, an authentication section, and an image forming section that forms an image on a sheet based on a print job,
• the print job is assigned terminal identification information that identifies the terminal device,
• the terminal device transmits the print job to the interface section,
• the interface section outputs, to the data storage section, the print job transmitted from the terminal device,
• the data storage section stores the print job output from the interface section
• the input section receives input information input by a user, and
• in accordance with whether or not the authentication section positively authenticates the user before a specified time elapses from the interface section receiving the print job from the terminal device, the interface section outputs the print job stored by the data storage section to the image forming section or the terminal device, and the data storage section deletes the print job stored.
