摘要： A clutch device includes a drive transmitting shaft; a driving-side engaging member; and a driven-side engaging member. A driving force is transmitted from the driving-side engaging member to the driven-side engaging member. The driving-side engaging member has a driving-side clutch tooth, and the driven-side engaging member has a driven-side clutch tooth capable of being engaged with and released from the driving-side clutch tooth. The driving-side clutch tooth and the driven-side clutch tooth have drive transmitting surfaces inclined so as to axially attracting each other in engagement with each other. At least one of the driving-side clutch tooth and the driven-side clutch tooth has a functional surface on a free end side relative to the drive transmitting surface with respect to the engaging direction. The functional surface is inclined so as to axially separating from a surface of the other clutch tooth in engagement therewith.

摘要： Electrostatic image graduations inclined by a first angle in a main scanning direction are formed on a photosensitive drum and transferred to an intermediate transfer belt, and electrostatic image graduations inclined by a second angle in the main scanning direction are formed on the photosensitive drum and transferred to the intermediate transfer belt so as to overlap with the electrostatic image graduations inclined by the first angle. The electrostatic image graduations inclined by the first angle are detected by a conducting wire having a linear conductive member inclined by the first angle in the main scanning direction of the intermediate transfer belt. The electrostatic image graduations inclined by the second angle are detected by a conducting wire having a linear conductive member inclined by the second angle in the main scanning direction of the intermediate transfer belt.

摘要： An image forming apparatus includes a first detector detecting an operation sound based on a sound wave received by a receiver; a second detector detecting basis weight of recording material based on an ultrasonic wave transmitted from a transmitter and received by the receiver; a switching unit that switches destination of a reception signal from the receiver between a first path to the first detector and a second path to the second detector; and a controller that controls the switching unit such that the reception signal is output to the first path at a first timing and to the second path at a second timing. When a predetermined condition is satisfied, the controller controls the switching unit such that the reception signal is output to the second path at the first timing or to the first path at the second timing.

摘要： An image forming apparatus includes a stack portion having recording materials, an image forming unit, a basis weight detection unit, an operating sound detection unit, and a mode selection unit. The basis weight detection unit detects a recording material basis weight based on an ultrasonic wave. The operating sound detection unit detect an abnormality of a generated operating sound. The mode selection unit selects, for each recording material fed to the image forming unit, between transmitting to the basis weight detection unit a first instruction for detecting the recording material basis weight and transmitting to the operating sound detection unit a second instruction for detecting the operating sound abnormality. In determining an interval at which each second instruction is transmitted, the mode selection unit determines the interval so that the interval and a cycle, in which properties of recording materials on the stack portion are repeated, do not continuously coincide.
