摘要： In an image forming apparatus in which toner is fed to a developer unit from a toner storage container through toner conveying means provided between the toner storage container and the developer unit, the image forming apparatus comprises a toner remaining amount detector for detecting not more than a predetermined amount of toner in the toner storage container, a toner density detector for detecting the density of toner in the developer unit, and means for interrupting the image forming operation to feed the toner to the developer unit from the toner storage container through the toner conveying means when the amount of the toner in the toner storage container is larger than the predetermined amount and the density detected by the toner density detector is lower than a predetermined density. Comsequently, suitable measures can be taken when there occurs such a state that no toner exists in the toner conveying means between the toner storage container and the developing mechanism even if the toner exists in the toner storage container.

摘要： A system for communicating data between two control units each capable of executing independent operations and having a memory for operations, the system is provided with a new data generator on one control unit. The new data generator generates new data for a selected item of the other control unit. The new data is combined with address data corresponding to the selected item of the memory of the other control unit to generate transmission data. The transmission data is sent to the other control unit and the new item data is written on the memory at the address specified by the transmission data. The data communication system communicates between the two control units data for a first kind of operations and data for a second kind of operations selectively. The first kind data is communicated repeatedly while the second kind data is communicated a single time.

摘要： An arrangement for communication between two CPUs which allows diagnosis of whether the cause of an interrupt in communication between the CPUs is due to a routine interrupt or a failure in the communication line. Timers generate overflow signals in the event that data from one or the other CPU is late in arriving. Lateness is determined by comparing the timer values to stored values in memory. Control units respond to the timers and switch the transmission level of the CPUs so that they pass a predetermined signal pattern between themselves, indicating that the interrupt is in effect but that communication lines are still open. When one of the CPUs fails to detect the confirmation signal, the CPU causes a communication failure to be indicated.

摘要： Upon restart of a job after the image forming apparatus is restored from document jam, a message that “If it is possible that the document might be damaged if fed by the document feeder, please press an escape key. If it is not possible that the document might be damaged even fed by the document feeder, please return a pack of documents to the original position” is displayed on a liquid display unit. A user checks the documents discharged and judges whether or not there is a possibility that the document might be damaged. When the user determines that there is a possibility that the document might be damaged, the user presses the “escape key”, and when the user determines that there is no possibility that the document might be damaged, the user presses a restart key.

摘要： An image forming apparatus so composed that it can be furnished with a plurality of developers, can change the developer opposed to the photosensitive body by integrally moving the corresponding developers and can compensate for the position of the corresponding developer at the compensating position thereof while changing developers. Furthermore, in the image forming apparatus, the developers are moved by a motor, the position of the developers is only compensated for when the predetermined compensating position is on a shortest moving path when changing one of the developers to another developer and the developers are always changed through the shortest moving path.
