ABSTRACT:
An image forming apparatus includes an image forming mechanism for forming an image and a matrix circuit having connected thereto a plurality of keys including an initiating key for instructing the start of image formation and a stop key for interrupting image formation. The image forming apparatus further includes a controller for controlling image formation by the image forming mechanism in accordance with a control sequence and a memory containing a program for sensing key input of the matrix circuit. Prior to the start of image formation, the controller executes the program for sensing key input of the matrix circuit and executes the control sequence in response to the sensing input of the initiating key. During image formation, the controller executes the program for sensing key input of the matrix circuit such that sensing whether the stop key has been input is executed without sensing whether the initiating key has been input.
