    Abstract: An optical scanning device includes a light source, a deflector, a scanning optical system, a BD sensor, and a half-silvered mirror. The light source emits a light beam. The deflector deflects a light beam emitted from the light source. The scanning optical system includes a scan lens and causes the deflected light beam to form an image on a photosensitive surface. The BD sensor detects a light beam. The half-silvered mirror splits the light beam into a first beam and a second beam. The first beam passes through the scan lens to enter the photosensitive surface. The second beam enters the BD sensor.

    Abstract: An image forming apparatus includes an image carrier, a developing device, a bias applying unit, a leakage detecting unit, a bias control unit and a leakage detection control unit. The developing device includes a magnetic roller and a developing roller. The magnetic roller carries a developer layer by being rotated. The developing roller receives the toner from the developer layer and supplies the toner to the image carrier. The leakage detection control unit performs a leakage detecting operation of detecting a value of an inter-peak voltage, at which the leakage occurred. The leakage detection control unit simultaneously starts the leakage detecting operation for a plurality of developing devices and performs the leakage detecting operations of the developing devices in which leakage simultaneously occurred while switching the leakage detecting operations one by one if the leakage simultaneously occurs in a plurality of developing devices at an inter-peak voltage.

    Abstract: A mounting auxiliary member includes a rotary member and a stationary member. The rotary member is provided in an optical scanning device, and interposed between a light source holding member holding a light source and a head part of a screw. The rotary member has a first through hole through which a shaft part of the screw penetrates and is configured so as to co-rotate with the screw as the head part of the screw comes into contact with a peripheral edge part of the first through hole. The stationary member is interposed between the rotary member and light source holding member, has a second through hole into which the shaft part of the screw penetrating through the first through hole is movably inserted, and is configured to hold the rotary member while permitting the rotary member to slidably rotate.

    Abstract: When rotation speed of second rotator is greater than or equal to a threshold previously determined, first control portion causes first generation portion to generate a first potential difference that enables toner in a predetermined amount to be transferred from first rotator to second rotator, and causes second generation portion to generate a second potential difference that enables the toner in the predetermined amount to be transferred from second rotator to a electrostatic latent image. When the rotation speed is less than the threshold, second control portion causes first generation portion to generate a third potential difference that enables the toner in an amount exceeding the predetermined amount to be transferred from first rotator to second rotator, and causes second generation portion to generate a fourth potential difference that enables the toner in the predetermined amount to be transferred from second rotator to the electrostatic latent image.
