摘要:
The present invention relates to a benzidine derivative represented by the general formula (3): wherein R 17 to R 24 are as defined in the present specification. The invention also relates to a benzidine derivative represented by the general formulae (3'), (4), (5) and (6), disclosed herein. The benzidine derivatives improve durability and heat resistance of a membrane containing the same while maintaining high hole transferring capability. Therefore, an electrophotosensitive material, which comprises a photosensitive layer containing the benzidine derivative, has high sensitivity and is superior in durability and heat resistance.

An image forming machine comprising a host computer, a printer, a copying machine, and a document supply device for conveying a document printed by the printer to an automatic document feeder of the copying machine includes a data switching controller which is connected to the host computer via a parallel data transfer type interface to selectively transfer data transmitted from the host computer to the printer side and to the copying machine side. The host computer sequentially puts out to the data switching controller a copying machine control code comprising an identification code with a predetermined number of bytes, and control data with a predetermined number of bytes succeeding the identification code, and print data for the printer subsequent to the copying machine control code.

An image forming apparatus is provided comprising means (5) for storing an objective model of the apparatus. The model includes specification of states (S) defined by physical parameters of the operational components (33, 36) of the apparatus. Also specified are behaviours (B) defined as changes in the states and functions which result from the various behaviours. The model is referred to as a function-behaviour state (FBS) diagram. Control means operate the apparatus under a control sequence for a particular function. When the function of the apparatus is defect, a substitute control sequence is activated. Redundancy system control means (8 - 14) are adapted to operate the apparatus under the substitute control frequency, whereby a lost function of one component can be replaced by a substitute function provided in another component.

A photosensitive drum unit for an image forming device includes a tubular member (31) having two openings (33) at the opposite ends thereof, two flange members (32) pressed into the openings of the tubular member (31), and an electroconductive ground plate (37) attached to one or both of the flange members (32). The ground plate (37) is provided with a plurality of projections (42, 45) formed integrally with the ground plate . The projections (42, 45) engage with the tubular member (31) in order to create an electrical connection between the photosensitive drum and the body of the image forming device.

A developing device includes a toner cartridge mounting portion, and a toner cartridge to be detachably mounted on the toner cartridge mounting portion. The toner cartridge mounting portion has a bottom wall having a toner acceptance opening formed therein, and a pair of supporting side walls disposed on the opposite side edges of the bottom wall, and an engaging means is disposed on the inner surface of one of the supporting side walls. The toner cartridge includes a generally cylindrical container having an unsealably sealed toner discharge opening formed in the peripheral wall of the container, and a toner accommodated in the container. An engaged means to be engaged with the engaging means is disposed in the outer surface of one side wall of the container. The one side wall of the container is opposed to the inner surface of the one of the supporting side walls to engage the engaging means and the engaged means with each other, and the other side wall of the container is opposed to the inner surface of the other of the pair of supporting side walls, whereby the toner cartridge is mounted on the toner cartridge mounting portion.
