3. Controlling the Development Characteristics (SALT)

a.

Outline
The printing density changes over time because of the following factors:
• Deterioration of the developer
• Deterioration of the photosensitive drum
• Changes in the environment
To make up for the changes, the density of the density pattern formed on the photosensitive drum is

measured by the SALT sensor, and the toner supply period is corrected based on the resulting
measurements.
