IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

摘要

An image forming apparatus includes an image density detector, an image forming device, a rotator, an image density controller, and a timing correction data obtainer. The image density detector detects a toner density of an image formed on an image bearing member. An image forming device forms the image using a density adjustable element that adjusts the density of the image. The rotator forms an image pattern while the density adjustable element is changed, and a density thereof is detected by the image density detector. The image density controller controls the image forming device using a density correction data for the density adjustable element corresponding to a rotational period of the rotator. The timing correction data obtainer obtains timing correction data for correction of driving timing of the image forming device based on a change in the density of the image pattern detected by the image density detector.

1. An image forming apparatus, comprising:
an image bearing member to bear an image on a surface thereof; a developer bearing member to supply toner to the image on the image bearing member to develop the image with toner; an image density detector to detect a density of toner in the image; an image forming device to form the image using a density adjustable element that adjusts the density of the image; a rotator to form an image pattern while the density adjustable element is changed, a density of the image pattern being detected by the image density detector; an image density controller to control the image forming device using a density correction data for the density adjustable element corresponding to a rotational period of the rotator to obtain a uniform image density; and a timing correction data obtainer to obtain timing correction data for correction of driving timing of the image forming device based on a change in the density of the image pattern detected by the image density detector, wherein as the image forming device is controlled by the image density controller using the density correction data, the density correction data is in a state in which the timing correction data obtained by the timing correction data obtainer is applied thereto.
