Abstract
An image forming apparatus including an image bearing member, a charger, an irradiator, a developing device, a transfer device, a neutralizer, and a varying device is provided. The neutralizer is adapted to neutralize the image bearing member by emitting neutralization light thereto, after a toner image formed on the image bearing member is transferred therefrom. The varying device is adapted to vary an amount of the neutralization light to be emitted to the image bearing member by pulse-width modulation of a voltage to be supplied to the neutralizer. The image forming apparatus satisfies the following formula:f/V>5wherein f (Hz) represents a frequency of the pulse-width modulation and V (mm/s) represents a linear speed of the image bearing member.
