摘要： A heater includes a base, a resistor pattern, and a circuit breaker. The resistor pattern includes a plurality of rows of resistors extending in a longitudinal direction of the base. The plurality of rows of resistors are spaced away from each other in a short-side direction orthogonal to the longitudinal direction of the base, coupled in parallel, and configured to generate heat by energization. The circuit breaker is disposed across the plurality of rows of resistors in the short-side direction and configured to cut off power supply to the resistor pattern when a temperature of any one of the plurality of rows of resistors reaches a high temperature threshold.

摘要： A separator for separating a recording medium from a fixing rotator includes a separation body including a front end and a conveyance path side face. The front end is disposed in proximity to an outer circumferential surface of the fixing rotator. The conveyance path side face faces a conveyance path where the recording medium is conveyed. At least one rotary separation aid projects beyond the conveyance path side face of the separation body toward the conveyance path. The rotary separation aid is rotated by the recording medium as the recording medium comes into contact with the rotary separation aid.

摘要： Toner images of different colors are superimposed on a transfer belt of an endless type from image carriers, to form a full color toner image. A tension roller maintains a tension of the transfer belt. A driving roller drives the transfer belt. A biasing unit applies the tension to the tension roller. A holding unit holds the tension roller. An image reading sensor detects the toner image formed on the transfer belt. The image reading sensor is disposed in the holding unit, in an opposite position to the tension roller with respect to the transfer belt.
