Inert gas is supplied from a supply source to the interior of a forming chamber through lines and gas supply routes. Variable flow control valves are provided in the middle of the lines and are controlled by a command from a control unit. The variable flow control valves vary pressure or flow rate of the inert gas in accordance with a command value to be sent every moment from the control unit such that the pressure or flow rate gradually reach a target value. According to the present invention, the pressure in the forming chamber is not varied abruptly when supply of the inert gas is stopped or the setting of flow rate thereof is changed. As a result, fluctuation in output of a load cell 8b can be suppressed and high precision of pressing force can be secured.

There is disclosed an image forming apparatus in which photosensitive member properties including potential properties of an exposed portion and unexposed portion of the surface of a photosensitive member irradiated with a light beam are estimated. An appropriate contrast potential and a developing bias voltage and charging grid bias voltage suitable for forming a high-density image are determined by a feedback control based on the photosensitive member properties. A laser power is changed to form an intermediate-density image whose density agrees with an intermediate-density target value. When the laser power is changed, the photosensitive member property changes. Therefore, the photosensitive member property is re-estimated, and the developing bias voltage and charging grid bias voltage are set again while maintaining the appropriate contrast potential.

A developing unit having a pair of semicircular first sealing members longitudinally formed on a cylindrical portion of both ends of a toner conveying roller along an outer peripheral surface of a toner conveying roller such that a gap is set between the sealing members and a toner layer thickness determining plate in a frictional state. A pair of second sealing members are provided close to a position where the toner layer thickness determining plate faces the roller and at a position, opposite to a side facing the toner conveying roller. Each of the first and second sealing members applies predetermined pressure to the toner conveying roller, and each of the sealing members includes lubricating fine grains.

The right and left front wheels of an asphalt finisher are each supported by a beam, one end of which is mounted to the body of the asphalt finisher by way of a pin such that the beam can swing, and the other end of the beam is mounted to the end of the piston rod of a hydraulic cylinder which is vertically mounted to the body of the asphalt finisher in a downward direction, both cylinders being connected to each other by way of a single oil line. As a result, when either one of the front wheels encounters an obstacle, the sideward inclination of the body can be eliminated.
摘要:
A toner sensor measures the amount of toner attached onto a photosensitive drum upon development by a developing unit. A controller compares the measured toner attaching amount with a predetermined reference value, and executes processing for changing at least one of image forming conditions, for example, the charging amount by a charger, the developing bias voltage of the developing unit, the exposure amount of an optical system, and the toner density of the developing unit, on the basis of the comparison result.
