摘要:
A developing device includes a developer container for accommodating one component magnetic toner; a rotatable toner carrying member, faced to an image bearing member for bearing an electrostatic image to form a developing zone therebetween, for carrying the toner in the container; a magnet member in the toner carrying member; a regulating member, elastically urged to the toner carrying member to form a nip therebetween, for regulating a toner layer thickness on the toner carrying member; wherein the magnet member has a magnetic pole, upstream of the nip with respect to a movement direction of the toner carrying member, for supplying the toner in the container to the toner carrying member, and wherein the magnet member does not generate a magnetic field effective for chain erection of the toner in a range from an upstream end of the nip to a downstream end of the developing zone.
摘要:
A timer for measuring the image formation interval, and the fixing temperature is set in response to the measured image formation interval so as to balance satisfactorily the degree of fixation, the amount of the recording material curling, and the recording material wrinkling no matter what timing is used to start the next image formation after the completion of the preceding one.
摘要:
An image forming apparatus which converts character or pattern information into bit map information (pixel information) and forms an image based thereon. The image forming apparatus includes a light-beam generator for generating a modulated light beam, a light-beam deflector for scanning an image carrier, a device for feeding a sheet to registration rollers and a driver for driving the image carrier. A time period is provided to operate the light-beam deflector and the feeding device before the driver starts to drive the image carrier to form an image.

An image forming apparatus includes a feeder means and a recorder. The feeder feeds a sheet of recording paper to a predetermined position in response to a spare paper feed signal instructing the feeding of the sheet of recording paper to the predetermined position preliminarily, and then feeds the sheet of recording paper being stopped at the predetermined position again in response to a record request signal. The recorder records an image on the sheet of recording paper fed by the feeder means through an electrophotographic process. The recorder means starts preparation to execute the electrophotographic process upon receiving the spare paper feed signal. As a result throughput is increased without causing other problems.

A position correction apparatus that corrects a position of a liquid ejection unit ejecting liquid toward a conveyed object includes a position detection unit configured to detect a position of the conveyed object in a width direction of the conveyed object, a moving unit configured to move the liquid ejection unit in the width direction, a moving amount determination unit configured to determine a moving amount of the liquid ejection unit in the width direction based on a position of the conveyed object in the width direction, a moving speed determination unit configured to determine a moving speed of the liquid ejection unit in accordance with a conveyance speed of the conveyed object, and a move control unit configured to control the moving unit so as to move the liquid ejection unit at the moving speed and by the moving amount in the width direction.
摘要:
Disclosed are a sheet conveying device and an ink jet recording apparatus capable of conveying a sheet in close contact with a drum without wrinkles. In a sheet conveying mechanism which presses a pressing roller against the front surface of a sheet being conveyed by a conveying drum to bring the sheet into close contact with the outer circumferential surface of the conveying drum, a back tension application device is provided at a position immediately before the sheet enters between the conveying drum and the pressing roller. The back tension application device sucks the front surface of the sheet to apply back tension to the sheet. Therefore, it is possible to prevent slackness of the sheet which enters between the pressing roller and the conveying drum and to prevent the occurrence of wrinkles.
