Abstract:
An image forming apparatus includes a latent image bearer, a charger to charge the latent image bearer with a charging bias obtained by superimposing a charge fluctuation voltage to reduce an image density fluctuation on a direct current charging voltage, a writing device to write a latent image on the latent image bearer with writing intensity obtained by superimposing fluctuating writing intensity to reduce an image density fluctuation on constant writing intensity, a developing sleeve to which a developing bias obtained by superimposing a fluctuating developing voltage to reduce an image density fluctuation on a direct current developing voltage is applied to develop the latent image, and circuitry to control the charging bias, the writing intensity, and the developing bias. The circuitry changes the charge fluctuation voltage and the fluctuating developing voltage depending on whether the writing device writes the latent image with the fluctuating writing intensity.

Claim (Index 7):
The image forming apparatus according to  claim 6 , further comprising a sensor to detect an image density fluctuation in a test image,\n wherein the developing sleeve to which the direct current developing voltage is applied forms a first test image, the sensor detects the image density fluctuation in the first test image, the circuitry generates first pattern data of the fluctuating developing voltage based on the image density fluctuation in the first test image detected by the sensor, the developing sleeve supplied with the direct current developing voltage and the fluctuating developing voltage fluctuated based on the first pattern data forms a second test image after the charger supplied with the direct current charging voltage charges the latent image bearer, the sensor detects the image density fluctuation in the second test image, the circuitry generates second pattern data of the fluctuating charging voltage based on the image density fluctuation in the second test image detected by the sensor, the developing sleeve supplied with the direct current developing voltage and the fluctuating developing voltage fluctuated based on the first pattern data forms a third test image after the charger supplied with the direct current charging voltage and the fluctuating charging voltage fluctuated based on the second pattern data charges the latent image bearer, the sensor detects an image density fluctuation in the third test image, and the circuitry generates third pattern data of the fluctuating writing intensity based on the image density fluctuation in the third test image detected by the sensor.
