Abstract: A fixing device includes a fixing member, a pressuring member, a separating claw separating a recording medium from the fixing member and a moving mechanism of the separating claw. The moving mechanism includes a biasing member, coaxial two input gears having different numbers of teeth, a bearing depression and a shaft protrusion. The two input gears rotate according to rotation the fixing or pressuring member while shifting by a difference of the numbers of teeth for each rotation. The bearing depression is depressed in one input gear, and has an inclined contact face. The shaft protrusion is protruded from the other input gear, and has an inclined distal end face contact with the contact face. The two input gears rotate to repeat coincidence of inclination directions of the contact face and the distal end face and shifting the inclination directions, and reciprocatingly move the separating claw.

Abstract: An electric device includes a substrate, a first wire, a filter, a storage portion, and a holding member. The first wire includes a base end portion that is electrically connected with a electronic circuit of the substrate. The storage portion includes a bottom portion and an inner peripheral portion. The storage portion stores the filter with the first wire inserted in a through hole thereof and stores a specific portion of the first wire. The holding member protrudes from the inner peripheral portion. The holding member includes an interposed portion and a position regulating portion. The position regulating portion abuts on the filter, from two sides of a second direction that is perpendicular to the first direction, and from one side of a third direction that is perpendicular to the first direction and the second direction, in such a way as to regulate a position of the filter.

Abstract: A drum unit of an image forming apparatus including a flange that is integrally provided with the photoconductor drum. A frame rotatably supports the photoconductor drum and covers its side. A gear portion is integrally formed with an outer circumferential surface of the flange. An outer diameter of the gear portion is larger than a diameter size of the photoconductor drum. A guide member is provided on an upper surface of the frame and guides the edge portion upward when the drum unit is pulled out of the apparatus main body. An upper surface of the guide member includes first and second guide surfaces. The first guide surface is located more on a side of a center of the photoconductor drum than the edge position, and the second guide surface is located more on the side of the insertion direction than the edge position.

Abstract: An image forming apparatus includes an image carrier, a first guide portion, a developing portion, and a second guide portion. The first guide portion forms a first flow path in which toner removed from the image carrier is flowed downward with respect to a horizontal direction. The developing portion visualizes an electrostatic latent image formed on a surface of the image carrier, with developer including at least toner and carrier. The second guide portion forms a second flow path in which the developer in the developing portion is flowed diagonally downward with respect to the horizontal direction and guided to the first flow path.
