Image forming apparatus that corrects image forming condition based on measurement result of measurement image

摘要

An image forming apparatus includes: a measuring unit configured to measure a plurality of measurement images, the plurality of measurement images including a first measurement image and second measurement images; a generation unit configured to generate a conversion condition based on second measurement data corresponding to the second measurement images; a first determination unit configured to determine an execution condition based on first measurement data corresponding to the first measurement image; and a second determination unit configured to determine a light intensity based on the first measurement data. A subsequent timing when the plurality of measurement images are to be formed is determined based on the execution condition, and an exposure unit updates the set light intensity to the light intensity determined by the second determination unit when the plurality of measurement images are formed at the subsequent timing.

1. An image forming apparatus comprising:
a converting unit configured to convert image data based on a conversion condition; a photosensitive member; an exposure unit whose light intensity is controlled, and configured to expose the photosensitive member based on the converted image data to form an electrostatic latent image; a developing unit configured to develop the electrostatic latent image to form an image on the photosensitive member; a transfer unit configured to transfer the image developed by the developing unit onto a sheet; a measuring unit configured to measure a plurality of measurement images formed on the photosensitive member by the exposure unit and the developing unit, the plurality of measurement images including a first measurement image and second measurement images; a controller configured to control the exposure unit and the developing unit to form the plurality of measurement images on the photosensitive member, and to control the measuring unit to measure the plurality of measurement images; a generation unit configured to generate the conversion condition based on second measurement data corresponding to the second measurement images measured by the measuring unit; and a determination unit configured to determine an execution timing and the light intensity of the exposure unit based on first measurement data corresponding to the first measurement image measured by the measuring unit, wherein the controller is further configured to control, based on the execution timing determined by the determination unit, a subsequent timing at which the plurality of measurement images are to be formed, wherein the controller is further configured to update the light intensity of the exposure unit to the light intensity determined by the determination unit at the subsequent timing, and wherein the conversion condition is updated before the subsequent timing.
