1. An image forming apparatus comprising:
a conversion unit configured to convert image data based on a conversion condition which corresponds to a type of halftone processing; an image processing unit configured to execute the halftone processing to the image data converted by the conversion unit; wherein the halftone processing includes first halftoning and second halftoning which is different from the first halftoning, a photoreceptor; an exposure unit configured to expose the photoreceptor to form an electrostatic latent image an image forming unit including
a photoreceptor,an exposure unit configured to expose, based on the image data that executed the halftone processing by the image processing unit, the photoreceptor with light to form an electrostatic latent image on the photoreceptor, anda developing unit configured to develop the electrostatic latent image; an image carrier on which a measurement image formed by the image forming unit; a measurement unit configured to measure the measurement image formed on the image carrier; a first generation unit configured to control the image forming unit to form a first measurement image which corresponds to the first halftoning, control the measurement unit to measure the first measurement image, and generate, based on the measurement result of the first measurement image by the measurement unit, a first conversion condition which corresponds to the first halftoning; a second generation unit configured to control the image forming unit to form a second measurement image which corresponds to the second halftoning after the first measurement image is formed, control the measurement unit to measure the second measurement image, and generate, based on the measurement result of the second measurement image by the measurement unit, a second conversion condition which corresponds to the second halftoning; and a determination unit configured to determine intensity of the light based on the measurement result of the first measurement image by the measurement unit during a time period between first timing and second timing, the first timing being a timing at which the image forming unit finished forming the first measurement image, and the second timing being a timing at which the image forming unit starts forming the second measurement image. |
