Patent ID: 8358946

Claim:
An image forming apparatus comprising: an image forming device which includes an image carrier, a charging unit configured to charge the image carrier, an exposure unit configured to form an electrostatic latent image by exposing the image carrier charged by the charging unit based on image data, a developing unit configured to develop the electrostatic latent image with a toner, and an intermediate transfer member on which a toner image developed by the developing unit is transferred, and is configured to transfer the toner image on a sheet; a first reading device configured to read a reference image which is formed on a sheet by the image forming device; a second reading device configured to read a reference image formed on the intermediate transfer member by the image forming device; a control device which can execute a first control process for adjusting image formation conditions for the image forming device based on a density of the reference image acquired from a read result of the first reading device, and a second control process for adjusting the image formation conditions based on a density of the reference image acquired from a read result of the second reading device; and a mounting detection device configured to detect that a unit configuring the image forming device has been mounted, wherein the control device executes the second control process before performing image formation based on the image data when the first control process has not been executed in a period from when mounting of the unit configuring the image forming device is detected by the mounting detection device to when the image formation is performed based on the image data.
