Title:
IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP2015049451
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To estimate a profile of a bow with high accuracy.SOLUTION: A control unit executes color registration correction except a bow (S100), drives a skew adjustment motor after the registration correction, to add an inclination to a second lens (S110), and writes a latent image of a registration mark on a photoreceptor drum via the second lens (S120). A registration sensor detects a registration mark M in a sensor depth position (S130). The control unit calculates a shift amount, which is a difference between a measurement value in the sensor depth position and an ideal value of an ideal profile in the sensor depth position O4 (S140), and acquires a shift amount in the center position associated with the shift amount in the sensor depth position, on the basis of the calculated shift amount, from a first table (S160). The control unit calculates a shift amount in a sensor-front position, and estimates a profile of the bow, on the basis of the shift amounts in the sensor depth position, the sensor-front position, and the center position (S170).
