Title:
IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP2013222131
Kind Code:
A
Abstract:

To provide an image forming device that collects transfer residual toner on an intermediate transfer belt into cleaners of photoreceptor drums, while preventing sensitivity of the photoreceptor drums from being deteriorated after long-term use due to exposure of the photoreceptor drums when inverse transfer electric field is formed during collection of transfer residual toner, resulting in reduction in image density or transfer residual toner collection failure.

When an inverse transfer electric field is formed during collection of transfer residual toner, at least one of charging bias voltage, primary transfer bias and exposure power to a photoreceptor drum is controlled on the basis of information on use of the photoreceptor drum.
