摘要： An image forming system which is capable of, when a manual stapling process is to be carried out on sheets, reducing waiting time for a user and decreasing power consumption. The image forming system has an image forming apparatus, which forms images on sheets, and a sheet post-processing apparatus. When the sheet post-processing apparatus is to shift into a power-saving state, a movable stapler is moved to a manual stapling position. When it is detected that sheets have been set into a sheet setting unit in a state in which the image forming apparatus and the sheet post-processing apparatus have shifted into the power-saving state, the image forming apparatus is held in the power-saving state, and the sheet post-processing apparatus is returned from the power-saving state.

摘要： An image forming apparatus that reduces density irregularity caused by SD gap variation. A developing bias voltage for forming a developing electric field between a photosensitive drum and a developing sleeve is applied to the developing sleeve. A rotational period of the photosensitive drum is divided into a plurality of blocks, and current values are acquired for each block. An average value of the acquired current values for each block is stored until the photosensitive drum is rotated a predetermined number of times, for each of the predetermined number of times of rotation. A moving average value of the average values in each block is calculated, and a correction table for correcting the developing bias voltage to be applied in each block is created using the calculated moving average values, and the developing bias voltage is controlled based on the created correction table.

摘要： Provided are a sheet feeding device and an image forming apparatus that are capable of accurately detecting an abnormality of a feeding state without erroneously detecting when a trailing edge of a preceding sheet and a leading edge of a subsequent sheet are fed in an overlaid state. The sheet feeding device includes ultrasonic wave sensors 6 and 7 that detect an overlaid state of a preceding sheet Sa and a subsequent sheet Sb fed from feeding portions 51, 317 to 319 and a controller 1 that continuously performs a detection of the overlaid state of a sheet fed from the feeding portion at a predetermined number of detecting points along a sheet conveying direction at every predetermined time and determines a number of detecting points where detects. Based on the determined number of detecting points, the controller determines that the overlaid state is normal or abnormal.

摘要： Provided is a sheet material binding apparatus capable of shortening a user's waiting time required to bind sheets through a manual operation with a movable stapler. A CPU (162) of a sheet material binding apparatus (50) monitors whether or not an image forming apparatus (1) can execute image formation processing. When the image forming apparatus (1) can execute the image formation processing, the movable stapler is arranged at a standby position close to the image forming apparatus (1). When the image forming apparatus (1) cannot execute the image formation processing, on the other hand, the movable stapler is arranged at a position for performing the manual operation, to thereby bind the sheets through the manual operation immediately.
