摘要： The image forming apparatus includes a CPU that performs control to form an inspection image for determining whether or not banding is suppressed to be smaller than a predetermined threshold value; and a density sensor that detects an intensity of banding periodically occurring in a sub-scanning direction of the formed inspection image. If based the detected banding intensity, the CPU has determined that the banding is not suppressed to be smaller than the predetermined threshold value, the CPU performs control to not perform banding correction or performs control to re-set a relationship between a phase of a rotary member and correction information.

摘要： A data communication control device. The data communication control device includes, a controller comprising a first data storing part, the first data storing part including multiple channels, each channel being applied to store a command for data transfer based on a destination of data, the controller executing the command stored in the channel from the head to transfer data and, an overall controller storing the command in the channel of the first data storing part when the number of commands in a certain channel is not over a upper limit, and stopping to store the command in the channel of the first data storing part and creating a second data storing part and storing the command in the second data storing part when the number of commands in a certain channel is over the upper limit.
