摘要： An image forming apparatus includes an image bearer, an image forming unit, a toner image detecting unit, and a detection processing unit. The image bearer is configured to bear a toner image. The image forming unit is configured to sequentially form groups of pattern images for a plurality of colors in a sub-scanning direction of the image bearer, each of the groups including pattern images of the same color at a predetermined interval. The toner image detecting unit is configured to detect the pattern images formed on the image bearer. The detection processing unit is configured to recognize whether an interval between adjacent pattern images of the same color corresponds to a set interval, to exclude an image for which the interval does not correspond to the set interval among the detected pattern images.

摘要： An image forming apparatus includes an image bearer, a driver, an image forming device, a sensor, and circuitry. The driver drives and rotates the image bearer. The image forming device forms a toner image on the image bearer driven and rotated by the driver. The sensor emits light to the image bearer and receives reflected light. The circuitry controls the driver and the image forming device to form a first toner image with a first color and a second toner image with a second color different from the first color. The circuitry controls the sensor to detect specularly reflected light and diffusely reflected light from the first toner image and the second toner image. The circuitry calculates an amount of misalignment of the first toner image and the second toner image based on a value of the specularly reflected light and a value of the diffusely reflected light.

摘要： A motor controller, operatively connected to a motor having an output shaft, includes a rotary detector to detect a rotation direction and a rotation amount of the output shaft of the motor to generate an actual rotary signal, a drive controller to generate a control signal based on the actual rotary signal and a target rotary signal indicating a target rotary direction and a target rotary amount, and a driver to supply a driving power to the motor based on the control signal. When the motor is in a hold state, the control signal is reversed periodically for a predetermined reverse time period T2 per a predetermined one reverse cycle T1. When the control signal is not reversed for a certain lock detection time period Tr that is longer than the revere cycle T1 of the control signal, supply of the driving power to the motor is blocked.

摘要： A water content measuring device measures water content of an object to be measured. The water content measuring device includes two plate members that are disposed facing each other, a current generating unit, a measuring unit, and an arithmetic processing unit. The current generating unit generates current supplied between the two plate members. The measuring unit measures electrostatic capacitance generated by the current supplied between the two plate members. The arithmetic processing unit is configured to convert the electrostatic capacitance measured by the measuring unit to water content. Two plate members each have a shape or are disposed such that at least two points on a leading edge of the object enter between the two plate members at different timings in a direction perpendicular to a passing direction in which the object passes through the two plate members.
