摘要： A supply control unit is configured to, in a successive image-forming operation, perform a process of successively generating a driving control pattern for a toner supply device based on image information of each page, and synthesizing an unused portion of the driving control pattern which is obtained by eliminating a portion of the driving control pattern already reflected on a driving control of the toner supply device from the driving control pattern generated based on image information of a previous page with a driving control pattern generated based on a subsequent page.

摘要： An image forming apparatus that includes a latent image carrier, a latent image forming unit, a developing unit, a toner supplier, a toner concentration detector, a prediction calculator, and a toner supply controller. The toner supplier includes a single driving source and supplies toner to a two-component developer at a predetermined supply position by driving a toner supply member with the driving source. The toner concentration detector detects a toner concentration in the developer at a predetermined detection position located upstream of the supply position. The prediction calculator predicts changes in the toner concentration in the developer over time at a prediction position located at the supply position or downstream of the supply position and upstream of a developer feed position to the developer carrier when toner is not supplied. The toner supply controller adjusts an amount of the toner supplied based on the prediction.

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.

摘要： An image forming apparatus includes at least one image bearing member, an intermediate transfer member, a secondary transfer member, and at least one optical sensor. In the image forming apparatus, it is determined that output values of the respective amounts of toner detected by the at least one optical sensor are affected by an impact caused due to a separation of the secondary transfer member from the intermediate transfer member and the output values are ignored as image adjustment input information, when the secondary transfer member separates from the intermediate transfer member during any of writing, developing, and transferring the plurality of image adjustment patterns, if the output values fall outside a given range and an interval between the output values of adjacent image bearing members is substantially equal to a distance between the two adjacent image bearing members for the primary transfer.
