摘要： A heater control system has a control circuit actuated in dependence upon an operation variable, such as time or heater temperature, to regulate the action of phase control means (4,5 or 4,11) in an AC power supply to the heater. Such regulation may be related to a transition period following the closing of the power supply circuit, or to the temperature of the heater (3), in order to limit surge currents when the heater is switched on. The system may be employed in an image forming apparatus wherein an image transferred onto paper is fixed thereto by being heated with a heater, the system controlling the heater so as to limit the power supply thereto when it detects that the power being used by other elements of the apparatus would otherwise give a total power consumption in excess of a predetermined maximum.

摘要： An image forming apparatus has the rotation of a fixing roller (14) controlled, said fixing roller being drivable by first and second motors (1,2), the first motor being driven at a higher speed than the second motor. The torques of the first and second motors are transmitted to a rotary shaft of the fixing roller through respective one-way clutches (7,8). The drive of the second motor is started immediately before the driving of the first motor is stopped at the end of an operation of the apparatus, and the drive of the second motor is maintained at least until the drive of the first motor is restarted. The continued low speed rotation of the fixing roller prevents it adhering to its backing or presser roller between operations.

摘要： An identifying means (60) of the manuscript-reading apparatus receives signals from a pair of sensors (31, 32) disposed on the manuscript conveying path while conveying a manuscript for reading image. In the event that the downstream side sensor remains OFF even when the upstream side sensor turns ON, identifying means then identifies the presence of a jammed manuscript. Only when both sensors (31, 32) turn OFF together, the identifying means (60) identifies the state of the release from the jammed manuscript.
