摘要： An image forming device includes a toner pattern forming unit that forms a first toner pattern and a second toner pattern downstream of the first toner pattern along a direction of advance of the transfer belt on the transfer belt. The first toner pattern is configured to include color patches of which a color density gradually differs so that, when detected by a sensor, a fluctuation of the toner density is adjusted by a feedback data. The second toner pattern is configured to prevent a cleaning blade from being twisted by a friction of an intermediate belt due to the toner lubrication.

摘要： An image forming apparatus includes an image carrying member, an image forming mechanism, an optical sensor, and a controller. The image forming mechanism performs an image forming operation for forming a reference toner image on the image carrying member under a specific setting associated with the image forming mechanism. The optical sensor is arranged in a vicinity to the image carrying member. The controller performs an optical toner test for checking, by using the optical sensor, optical characteristics of the reference toner image formed on the image carrying member and to adjust the specific setting based on a result of the optical toner test.
