If image stabilization becomes necessary while an MFP is executing a print job received from a user, the MFP performs the image stabilization while emitting an operation sound if the user has not moved away from the MFP. Also, if the user has moved away from the MFP, the MFP stops the print job and logs the user out.

A power supply control device controls a power supply connected to a motor and includes: an AC/DC converter that makes a first DC power supply; a DC/DC converter that makes a second DC power supply out of the first DC power supply; a first rectifying element that allows current to flow from the first DC power supply toward the motor; a second rectifying element that allows current to flow from the first DC power supply toward the DC/DC converter; and a third rectifying element that allows current to flow from the motor toward the DC/DC converter. In this way, a power supply connected to a motor can be suitably controlled.

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.

An image forming apparatus according to the invention comprises: a cartridge loading portion removably loaded with a first cartridge containing therein a consumable but carrying no memory storing information on the consumable, or with a second cartridge containing therein the consumable and carrying a memory storing information on the consumable; a controller; and a first memory storing the information on the consumable contained in the first cartridge, and is characterized in that the controller includes: a first consumption calculating/storing portion operating when the first cartridge is loaded in the cartridge loading portion, calculating a consumption of the consumable in the first cartridge and storing the calculation result in the first memory; and a second consumption calculating/storing portion for calculating a consumable consumption of the second cartridge and for storing the calculation result in the memory installed in the second cartridge.
摘要:
A hydraulic cylinder type high damping device in which a cylinder member or a piston rod member is connected to the frame of a structure and the other member is connected to an earthquake-resisting element integrally secured to the frame. A plurality of passages through the piston connect hydraulic chambers on opposite sides of the piston. The passages are provided with pressure-governing valves which control the flow of oil between the hydraulic chambers. In addition, an accumulator system provides a bypass for oil to flow between the hydraulic cylinders in order to modulate the oil pressure in the damping device. Relief valves are provided in parallel with the pressure governing valves to provide a variable damping coefficient which protects the damping device from overloads caused by excessive seismic shock.

In an image forming apparatus, a control circuit rotationally drives a development roller at a predetermined rotation speed during a development process, in which the development roller has depression portions and land portions on a circumferential surface. The depression portions and the land portions are oblique grooves in the surface. While the development roller is rotationally driven, the control circuit controls the predetermined rotation speed such that a crossing angle approximates 90°. The crossing angle is formed by a screen line in the electrostatic latent image on the circumferential surface of the latent image support and an area where the land portion of the development roller substantially passes over the circumferential surface of the latent image support.
