Abstract: The fixing device includes a fixing member, a pressing member, and a heat source. The fixing member heats toner on a medium. The pressing member forms a pressing area with the fixing member and presses the toner. The heat source is provided corresponding to the pressing area across the fixing member and heats the fixing member. The heat source includes a heat insulation layer and a heating and contacting part. The heat insulation layer is laminated on a base material and has a convex part that protrudes toward the fixing member. The heating and contacting part is laminated on the heat insulation layer that has the convex part and contacts to an inner surface of the fixing member so as to heat the fixing member. The convex part protrudes the heating and contacting part laminated thereon toward the fixing member so as to maximize pressure in the pressing area.

Abstract: A fixing device includes a cylindrical rotatable fixing belt, a flat heater, a safety device, a heater holding part and a pressuring member. The flat heater has a plurality of heat generating parts. The safety device is arranged across two adjacent heat generating parts to interrupt power supply to the heat generating parts in a case where temperature reaches a threshold value. The heater holding part holds the flat heater so that the flat heater comes into contact with an inner circumference face of the fixing belt. The pressuring member sandwiches the fixing belt with the flat heater to form a pressuring area for sandwiching and conveying a sheet between the fixing belt and the pressuring roller.

Abstract: A paper feed device includes a plurality of paper feed sections and a selection control section. Selection periods include a specific selection period during which at least two selection signals among a plurality of selection signals are not at a normal level. Non-selection periods include a first normal period, a second normal period, a preceding non-selection period, and a succeeding non-selection period. The preceding non-selection period is between the first normal period and the specific selection period. A specific selection signal among the at least two selection signals is switched from the normal level to a selection level during the preceding non-selection period. The succeeding non-selection period is between the specific selection period and the second normal period. The specific selection signal is switched from the selection level to the normal level during the succeeding non-selection period.

Abstract: An image forming apparatus includes a plurality of heaters, a switch portion, and first and second supply lines. The heaters heat a toner image. The switch portion is connected to an alternating-current power source, and opens and closes in a manner interlocked with the opening and closing of a cover. The first supply line connects the respective one ends of the heaters to the switch portion. The second supply line connects the respective other ends of the heaters to the switch portion. The second supply line has a branch portion. The respective other ends of the heaters are each connected to one of branch lines which are electric wires that branch off from the branch portion. The switch portion is disposed between the branch portion and the alternating-current power source.

Abstract: An image reading device has a motor, an optical sensor (a light emitting portion, a light receiving portion), a carriage, a motor, a moving portion for rotating a belt, a pulse generating gear provided with a plurality of light shielding teeth along its circumference, and a control portion. The light shielding teeth of the pulse generating gear pass through a gap between the light emitting portion and the light receiving portion. First and second widths are set such that the movement amount of the pulse generating gear resulting from the motor rotating one step is equal to or larger than both the width of each of the light shielding teeth (first width) and the width of the interval between adjacent light shielding teeth (second width). The control portion recognizes when, during standby of the carriage, the level of an output signal changes.
