Abstract
An apparatus includes an irradiation unit configured to irradiate a light onto a toner image, a detection unit configured to detect reflected light from the toner image, and a deriving unit configured to derive a toner adhesion amount of the toner image, based on detection result by the detection unit in measurement range of integer multiple of screen pitch of the toner image.
Claims13
An apparatus for measuring a toner adhesion amount of a toner image formed on an image bearing member of an image forming apparatus, the apparatus comprising:
- an irradiation unit configured to irradiate light on the toner image;
- a detection unit configured to detect reflected light from the toner image;
- and
- a deriving unit configured to derive the toner adhesion amount, based on detection result by the detection unit in measurement range of integer multiple of screen pitch of the toner image.
An apparatus comprising:
- an irradiation unit configured to irradiate a light onto a toner image formed on an image bearing member of the apparatus;
- a detection unit configured to detect reflected light from the toner image;
- a deriving unit configured to derive a toner adhesion amount of the toner image, based on detection result by the detection unit in measurement range of integer multiple of screen pitch of the toner image;
- and
- an image forming unit configured to form an image based on set value corrected based on the derived toner adhesion amount.
A method for measuring a toner adhesion amount of a toner image formed on an image bearing member of an apparatus, comprising:
- irradiating a light onto the toner image;
- detecting a reflected light from the toner image;
- and
- deriving the toner adhesion amount of the toner image, based on detection result of the detection in measurement range of integer multiple of screen pitch of the toner image.
