An image recording system includes two image recording apparatuses each capable of recording images independently. A color image recording apparatus is disposed with a bypass transporting path apparatus. A transporting path connecting apparatus is disposed between the front of a monochrome image recording apparatus and the back of the color image recording apparatus. A final processing apparatus that is common to the color and monochrome image recording apparatuses is disposed in the front of the color image recording apparatus. The system includes a process switching portion that, when arrival of a recorded item at the recorded item containing portion by one image recording apparatus on the side that executes an image recording process of the color image recording apparatus and the monochrome image recording apparatus is late for that by the other image recording apparatus, switches the process to a substitute image recording process by said other image recording apparatus.

When a front cover of a body of a printer is opened, a count value in a system RAM included in a printer body control processor is recorded in a counter in an E.sup.2 PROM included in a process cartridge through a system bus and an input/output port. On the other hand, when the front cover of the printer body is closed, a count value of the E.sup.2 PROM is recorded in the counter in the system RAM. Even in the case where a main switch is turned off, electric power from a receptacle is supplied to each control circuit through a transformer.

An improved laser printer having a density sensor which reads a density of an automatic image density control (AIDC) mark formed outside an image area on a photoconductor 2. A CPU controls a solenoid based on an output of the density sensor and regulates the amount of toner supply to a developing device. A start counter and an end counter define a start position and an end position in both the primary scanning direction of the image area and in the main scanning direction of the AIDC mark. The start and end positiones are based on timer values set in their respective counters.

A data communication system for the communication between two different data transmission systems, the SDT system and the RDT system. The SDT system includes a host CPU having an output terminal for repeatedly producing first data in a predetermined sequence of time slots by a number of interruptions taken in each time slot, a bus structure extending from the output terminal of the host CPU for transmitting the data, and a plurality of slave CPUs, each having an input terminal connected to the bus structure for receiving the first data. The RDT system for the data transmission between at least first and second CPUs includes a RAM for storing a command to the second CPU. The first CPU is operative to write the command into the RAM. The first command writing takes place at a first predetermined pulse period in a predetermined sequence of pulses. The second CPU reads the command from the RAM at a second predetermined pulse period. The host CPU in the SDT system is used in common with the first CPU in the RDT system. Also, the sequence of time slots have at least one time slot which is sufficiently long to include the sum of one cycle of the predetermined sequence of pulses and one pulse period for carrying out the data transmission by the second data transmission system within one time slot.

There is disclosed a lubricant the major portion of which is composed of Duomeen-T-dioleate. It may be associated with a diamide compound of the formula ##STR1## wherein R.sup.1 is a C.sub.2-4 alkylene radical and R.sup.2 is a C.sub.14-18 alkyl or alkenyl radical, or with various kinds of thickeners and/or waxes. The resulting lubricant has superior performance when applied to a metal-metal, metal-plastics or plastics-plastics sliding surface.
