An image forming system includes an image forming apparatus and a mobile terminal. The image forming apparatus forms an image on paper. The mobile terminal communicates with the image forming apparatus through a communication network. Mode information is inputted to the image forming apparatus from an external device. The mode information indicates a quiet mode in which an image is formed at a predetermined formation speed, or a normal mode in which the image is formed at a faster formation speed than the quiet mode. The quiet mode is settable on the mobile terminal. The image forming apparatus forms an image in the quiet mode when the mode information inputted from the external device indicates the normal mode and setting information indicating the quiet mode is acquired from the mobile terminal.

An image forming system includes an image forming apparatus and a mobile terminal. The mobile terminal communicates with the image forming apparatus through a communication network. Mode information is inputted to the image forming apparatus from an external device. The mode information indicates one mode among a quiet mode in which an image is formed at a predetermined formation speed, a normal mode in which the image is formed at a faster formation speed than the quiet mode, and an urgent mode in which an image forming process in the quiet mode or the normal mode is interrupted to form the image. The quiet mode is sellable on the mobile terminal. The image forming apparatus forms the image in the urgent mode when the mode information inputted from the external device indicates the urgent mode and setting information indicating the quiet mode is acquired from the mobile terminal.
