Abstract
In an image forming system including a plurality of image forming apparatuses, a malfunction in a transmission interface of each image forming apparatus can be recognized before a transmission of image data is performed and a malfunctioning position can be easily specified. Each image forming apparatus includes an interface unit transmitting encoded image data and also receiving image data from a remote image forming apparatus. The image forming apparatuses are connected by a transmission path so that the encoded image data is transmitted therebetween. The interface unit is subjected to a diagnosis operation when a power of each image forming apparatus is turned on.
