Abstract
A sheet conveyance device includes a pair of separable contact rollers configured to convey a sheet, a contact/separation mechanism configured to support the pair of separable contact rollers in such a manner that the pair of separable contact rollers are able to come into separable contact with each other, and a solenoid configured to operate the contact/separation mechanism. The solenoid is driven so that the contact/separation mechanism causes the pair of separable contact rollers to come into pressure contact with each other, and driving of the solenoid is cancelled so that the contact/separation mechanism causes the pair of separable contact rollers to be separated from each other. Pulse width modulation duty control is performed on the solenoid while the pair of separable contact rollers are in pressure contact with each other when a plurality of the sheets are conveyed one by one at an interval.
