摘要： In an image forming apparatus according to the present invention, a software portion incorporated in the apparatus is provided with a virtual case storage portion 12, to previously create virtual cases by a virtual case compiler 16 outside of the apparatus and store the virtual cases. Fault diagnosis is made by comparing fuzzy qualitative values into which the values of sensors are converted on the basis of fuzzy membership functions with the virtual cases. If a fault is diagnosed as a result of the comparison, repair operations for repairing the fault are read out from a work script table 15. In this case, operation information for repair is stored to correspond to each of a plurality of domains into which a state space which the apparatus can take up is divided. Accordingly, it is possible to correctly read out corresponding repair operations from the work script table 15 depending on which of the domains is a domain to which the present state of the apparatus belongs. As a result, a self-repair system can be constructed as a practical built-in type system, thereby to make it possible to reduce the scale of the system related to the fault diagnosis as well as to reduce time required for the fault repair.

摘要： There is provided a toner for a two-component type developer, which comprises (i) toner particles comprising a fixing resin having anionic polar groups, a coloring agent, and a magnetic powder which is used in an amount of 0.1 to 5 parts by weight for 100 parts by weight of the fixing resin, and (ii) an additive comprising silica, alumina and titania, and being adhered on surfaces of the toner particles in a total amount of 0.15 to 2 parts by weight for 100 parts by weight of the toner particles, and contains substantially no charge control agent. The toner exhibits a stable chargeability during a long-term use without generation of a spent toner. As a result, the toner suppresses the image fogging and the toner scattering, and ensures a stable image density and a high image quality for a long term.

摘要： A sheet transportation device for use in an image forming apparatus is provided which has self-diagnosis and self-repair functions. The sheet transportation device has a sheet transportation system comprising a plurality of units (8). A control sequence for a sheet transportation operation is applied from a system body (10) to the respective units (8). The units (8) each execute the control sequence to perform the sheet transportation operation. The units (8) are each constructed so as to perform an autonomous operation. This construction allows the respective units to autonomously perform self-diagnosis and repair operations. The fault diagnosis and repair operations are performed in parallel to the sheet transportation control. Therefore, the sheet transportation device can flexibly adapt itself to an external influence such as a change in the use environment and a malfunction due to a time-related change such as the aging of components thereof. Thus, the sheet transportation device ensures a highly reliable operation and yet requires less labor for the maintenance and inspection.

摘要： A sheet transportation device is provided which has a self-repair function and is capable of performing functional maintenance for sheet transportation. The sheet transportation device includes a plurality of transportation-related units (8) disposed in a predetermined order to define a transportation path (7) and each having a function of autonomously performing a sheet transportation-related operation on the basis of a control sequence applied thereto. Predetermined physical quantities concerning the respective transportation-related units (8) are sensed and the sensed physical quantities are stored as those indicative of the states of the transportation-related units (8). If any of the states of the transportation-related units (8) thus stored corresponds to a particular state, e.g., a faulty state, a control sequence is prepared by utilizing the states of the transportation-related units (8) and knowledge information concerning a sheet and the transportation path (7). The control sequence prepared in consideration of the states of the transportation-related units (8) is applied to the transportation-related units (8) for implementation of a self-repair function.
