Abstract:
1. An image forming apparatus for forming an image using a toner comprising: a developer container configured to contain the toner; a density measuring sensor configured to measure the toner density in said developer container; a developer carrying member configured and positioned to develop an electrostatic latent image formed on an image bearing member using the toner in said developer container; a toner replenishing member configured and positioned to supply said developer container with the toner in a toner replenishing container; a controller configured to obtain data representing the number of rotations of said toner replenishing member based on the toner density measured by said density measuring sensor; and a memory configured to store correction information according to the number of rotations of said toner replenishing member, wherein said controller corrects the data representing the number of rotations of said toner replenishing member using the correction information stored in said memory, and controls the supply of toner to said developer container by controlling the rotation of said toner replenishing member based on the corrected data.
