Title:
IMAGE-FORMING DEVICE
Document Type and Number:
Japanese Patent JP2023102996
Kind Code:
A
Abstract:
To reduce a difference in abrasion in a longitudinal direction of a photoreceptor while restraining an amount of consumption of toner.SOLUTION: An image-forming device 1 includes: a photoreceptor 31 for carrying an electrostatic latent image; an exposing device 33 for forming an electrostatic latent image in the photoreceptor 31; a development part 34 for developing a developer containing toner TN to which an external additive containing a fatty acid metal salt particle is added to an electrostatic latent image; average image density calculation means 60 for dividing an image formation area 4 of a photoreceptor 31 into multiple areas AR in a direction crossing a rotation direction and calculating an average print Duty for each of the multiple areas AR; and developer disposal means 62 for disposing the toner TN onto the photoreceptor 31 on the basis of a difference between the average print Duty for each of the multiple areas AR and the average Duty of an adjacent area that is adjacent to each area AR.SELECTED DRAWING: Figure 5
