摘要:
An imaging device includes an imaging element, a shutter mechanism, an actuator, a rotatable transmission member, a position detector, and a drive controller. The shutter mechanism is switchable between an open and a closed state to control the light incident on the imaging element. The transmission member is configured to transmit a driving force produced by the actuator to the shutter mechanism. The position detector is configured to detect the rotational position of the transmission member. The drive controller is configured to direct the actuator to begin storing the driving force while image data is being read from the imaging element, to control the timing at which the actuator begins driving the shutter mechanism based on the position of the transmission member detected by the position detector, and to switch the shutter mechanism from the closed state to the open state after the actuator has stopped storing the driving force.

An image forming apparatus includes an image bearing member for bearing a developer image; a developing device including a developer carrying member for forming the developer image on the image bearing member; a fixing device for fixing the developer image on a sheet material, on which the developer image has been transferred, by heating the sheet material; a memory medium for storing an operation hysteresis value, of the developing device, which varies depending on a state of an operation of the developing device from start of the operation; and a controller for controlling a temperature of the fixing device. The controller controls, when the operation hysteresis value stored in the memory medium reaches a preset threshold, the temperature of the fixing device so as to be lower than that before the operation hysteresis value reaches the preset threshold.
