An image forming apparatus is used in conjunction with a signal generator for producing an image signal representing an image to be recorded. The apparatus includes a device for forming a visible image with visible material on an image bearing member. The image is represented by the image signal produced by the signal generator. A time signal is also generated by a time signal generator and a measuring circuit measures the time signal so generated as a function of the production off the image signal by the image signal generator. Finally, a warning signal that indicates insufficiency of supply of the visible material for forming an image properly by the image forming device is produced on the basis of measurement of the time signal by the measuring circuit.

摘要:
An image forming system for forming an image on a recording sheet, including a rotatable image bearing member, a cleaning member contacting the image bearing member to remove toner remaining on the image bearing member, and charger means contacting the image bearing member and disposed at a downstream side of the cleaning member in a direction of movement of the image bearing member. Lubricant having a low resistance is painted on a contacting portion of the cleaning member between the image bearing member and the cleaning member.
摘要:
A process of producing a cleaning blade including a silicon rubber base and a resin layer which acts as a lubricant on the surface of the rubber is produced by molding a rubber material having resin powder dispersed therein at a temperature less than the softening or melting point of the resin, cutting an end of the rubber, and vulcanizing the molded rubber at a temperature higher than the softening or melting point of the resin. The resin layer is selected from polypropylene, polyvinylidene fluoride, polyethylene, or polyester.
