Image forming apparatus for forming a measurement image

摘要

An image forming apparatus includes a measurement unit configured to irradiate a measurement image with light, and measure the light reflected from the measurement image, a white reference plate disposed in a position opposite to the measurement unit, a correction unit configured to correct a measurement result of the measurement image, based on a measurement result of the white reference plate acquired by the measurement unit, and a temperature detection unit configured to detect temperature in a vicinity of the measurement unit, wherein the correction unit corrects, in a case where a difference between a temperature detected by the temperature detection unit and a temperature shown when previously measuring the white reference plate is less than a predetermined value, a measurement result of the measurement image using a previous measurement result of the white reference plate without measuring the white reference plate with the measurement unit.

1. An image forming apparatus comprising:
an image forming unit configured to form a measurement image on a sheet; a measurement unit configured to irradiate the measurement image with light, and measure the light reflected from the measurement image; a white reference plate disposed in a position opposite to the measurement unit; a correction unit configured to correct a measurement result of the measurement image, based on a measurement result of the white reference plate acquired by the measurement unit; and a temperature detection unit configured to detect temperature in a vicinity of the measurement unit, wherein the correction unit corrects, in a case where a difference between a temperature detected by the temperature detection unit and a temperature shown when previously measuring the white reference plate, is less than a predetermined value, the measurement result of the measurement image using a previous measurement result of the white reference plate, without measuring the white reference plate with the measurement unit.
