Abstract

Official abstract text for this publication.

An image forming apparatus includes a photoconductor drum, a latent-image forming device, a developing device, a density detecting device, and a processing device. The density detecting device is configured to detect densities at a plurality of positions in a main-scanning direction on a developed image. The processing device is configured to acquire at least two light-amount correction tables respectively associated with at least two positions of the plurality of positions in the main-scanning direction on the developed image, the light-amount correction tables being for reducing density variations in a sub-scanning direction at the at least two positions, and correct, for each scan, a set point for setting an amount of light of a light source based on a difference in corresponding correction data between two light-amount correction tables respectively associated with two adjacent positions of the at least two light-amount correction tables.

First claim

Opening claim text (preview).

What is claimed is: 1. An image forming apparatus comprising: a photoconductor drum; a latent-image forming device including a light source and configured to scan a surface of the photoconductor drum with light from the light source in a main-scanning direction to form a latent image on the surface; a developing device configured to develop the latent image into a developed image; a density detecting device configured to detect densities at at least four positions in the mai…
