摘要： When a printing instruction is provided, a CPU causes a stepping motor M to drive a developer and calculates the value of a load of the stepping motor M before printing operations are performed. Then, CPU determines whether the value of the load is within a predetermined range stored in advance. If the value is not within the predetermined range, CPU causes a display to display an error message.

摘要： Upon completing a preparation operation including different processes, an image formation apparatus shifts to ready state in which image formation is executable, the processes including at least one process executed using a corresponding motor. The image formation apparatus comprises: an obtainer for obtaining, for each process, an estimated time period between start and completion thereof; and a controller for starting execution of, out of the processes, (i) one process whose estimated time period is the longest, then (ii) any other process so that any other process is executed in parallel with said one process. When said one process is included in the at least one process, the controller initiates the motor by high-speed initiation by applying thereto first voltage that is higher than second voltage. When any other process is included in the at least one process, the controller initiates the motor by normal initiation by applying thereto first voltage.

摘要： An image forming apparatus has a toner carrier and a toner passing control having a plurality of toner passing holes for controlling passage of a toner. The toner passing control has upstream side secured, the downstream side extended by a spring, and is contacted with a stay on the downstream side of the contact point with the toner carrier, so that corrugation deformation is prevented. A vibrating plate and an ultrasonic vibration generator are coupled through a coupling portion, thereby relative displacement between the vibrating plate and the ultrasonic vibration generator is allowed. A detachable toner cartridge is formed by integrating a developing roller and a toner storing container.

摘要： Rotational force of a driving motor is transferred to a photosensitive drum via a planetary-roller reduction device, so that the photosensitive drum is rotated. A speed detector set on the shaft of the photosensitive drum detects the rotational speed of the photosensitive drum. In accordance with the detected rotational speed of the photosensitive drum, the rotational speed of the driving motor is adjusted so that the photosensitive drum is rotated at a constant speed.
