    摘要： An image forming unit forms a toner image on an image carrier, and transfers the toner image to a recording medium. A voltage generation circuit generates a high voltage used for the image forming unit. A control circuit is connected to the voltage generation circuit via a cable, and controls the high voltage generated by the voltage generation circuit. A detection unit detects a current flowing in a load of the image forming unit to which the high voltage generated by the voltage generation circuit is applied. A determination unit determines an error in accordance with a current range in which the current detected by the detection unit falls. The current range is included among a plurality of current ranges that are in one-to-one correspondence with a plurality of errors.

    摘要： An image forming apparatus capable of reducing an image defect even when an container is rotated for checking. A development unit forms an image by developing an electrostatic latent image on a photosensitive member. A drive unit rotates the container mounted to a mounting portion for replenishing the toner to the development unit. An output unit outputs a specified signal when detecting a predetermined portion of the container. A determination unit determines whether the container is mounted to the mounting portion according to the specified signal. A decision unit decides a toner replenishing amount based on image data. A controller controls the drive unit to execute a detecting operation that rotates the container when the determination unit does not determine that the container is mounted. A correction unit corrects the toner replenishing amount based on the output of the output unit when the detecting operation is executed.

    摘要： A sheet binding processing apparatus for avoiding the residual of binding member is provided. The sheet binding processing apparatus comprises a sheet insertion port through which a sheet bundle formed of a plurality of sheets S is inserted, a movable stapler for binding the sheet bundle inserted through the sheet insertion port, and a manual stapling sheet sensor for detecting, at a predetermined detection time interval, existence or non-existence of the sheet bundle in the sheet insertion port. When the manual stapling sheet sensor detects the existence of the sheet bundle, the sheet binding processing apparatus gives permission to bind the sheet bundle by the movable stapler.

    摘要： An image forming apparatus includes a waste toner container for containing toner recovered from a photosensitive drum and an intermediate transfer belt. The waste toner container has a stirring screw for conveying the toner in the waste toner container. The stirring screw is driven by a waste toner motor. A CPU determines whether the waste toner container is in need of replacement depending on a rotation speed or driving current of the waste toner motor. If the waste toner container is in need of replacement, the CPU displays such on a display unit to provide a notification to a user.
