A vehicle seat includes: a seat back, connected with a seat cushion through a recliner, an outlet of a shoulder belt being provided in one shoulder of the seat back, wherein: the seat back includes: a first side frame, arranged on the one shoulder side; and a second side frame, arranged on the other shoulder side; the first side frame includes: a first frame member having a hollow and closed sectional shape; and a plate-shaped bracket which is attached in the recliner; and the bracket includes a joint part which is inserted into a lower end portion of the first frame member and is joined with the lower end portion.

Vehicle seat

A vehicle seat includes: a seat back; and a seat cushion including: a first side frame; a second side frame; a front frame connecting front end portions of the first side frame and the second side frame to each other; and a rear frame connecting rear end portions of the first side frame and the second side frame to each other. The first side frame includes: a frame member including a closed sectional shape part between the front frame and the rear frame; a first reinforcing member being provided between the front frame and the rear frame to pass through an inner side wall and an outer side wall, and being joined with the inner side wall and the outer side wall; and a connection member connecting an end portion of the first reinforcing member with at least one frame of the front frame and the rear frame.

An image forming apparatus has a fixing unit. A heat roller heats a toner image on a print medium to fuse the toner image. A first temperature detector is in contact with a longitudinal end portion of the heat roller, and generates a first temperature data. A second temperature detector opposes the heat roller and is in proximity to a substantially middle portion of the heat roller. The second temperature detector generates a second temperature data. Depending on the first temperature data and the second temperature data, a controller performs temperature control either in a first mode where the heater is energized such that the first temperature data is equal to a first target value, or in a second mode where the heater is energized such that second temperature data is equal to a second target value.

Image forming apparatus

A method of forming an electrostatic latent image includes printing operation and toner recovering operation. The printing operation includes charging, forming an electrostatic latent image, developing, and transferring operations. The toner recovering operation includes the step of charging the photosensitive drum in timed relation to the rotation of the photosensitive drum after printing operation so that reversely charged toner deposited on the charging roller migrates from the charging roller to the photosensitive drum. The toner migrated from the charging roller to the photosensitive drum is recovered into a developer. An apparatus for forming an image includes a charging roller, photosensitive drum, developing roller, and transfer roller. The apparatus further includes a reversely-charged-toner recovering device which causes the photosensitive drum to be charged in timed relation to the rotation of the photosensitive drum after printing operation so that the reversely charged toner deposited on the charging roller migrates to the photosensitive drum. The developer recovers the toner which has migrated to the photosensitive drum from the charging roller.

A toner image processing apparatus performs a printing operation and a cleaning operation. A toner-attracting electrode includes first and second electrodes disposed closer to the charged surface of a photosensitive drum and outside of a path through which the light from the exposing device illuminates the charged surface. During the toner attracting operation, a toner-recovering device causes the toner-attracting electrode to attract the toner particles floating in the air surrounding the exposing device, and reversely charged toner particles and residual toner particles left on the photosensitive drum after the toner image is transferred to the print medium. During the toner-releasing operation, the toner-recovering device causes the toner-attracting electrode to release the attracted toner particles to the photosensitive drum. The toner-attracting operation is performed during the printing operation and the toner-releasing operation is performed during the cleaning operation.

An apparatus controls a temperature of a heat roller for fixing a developer material transferred on a print medium such as paper. The apparatus includes a controller, a sensor for detecting the thickness and/or width of a print medium such as paper, and a temperature-detecting element such as a thermistor for detecting the temperature on a first surface of the heat roller outside of a second surface area of the heat roller in contact with the print medium. The controller controls the temperature of the heat roller in accordance with the dimension of the print medium so that the middle portion of the heat roller is maintained substantially at a temperature of a first predetermined value during continued printing operation. The controller raises the temperature on the first surface stepwise in accordance with each page of the print medium during continued printing operation till the temperature on the first surface reaches a temperature of a second predetermined value, and maintains thereafter the temperature on the first surface at the second predetermined value during continued printing operation.

A fusing apparatus 14 for fusing toner onto paper includes a heater roller 2 and a separating unit 15 with a separation claw 16. The separation claw 16 is provided with a paper guide member 17 having a curvature in a direction opposite to the curvature from a point a to a point c on the heater roller 2. After fusing, the front end 10a of the separated paper 10 is guided by the paper guide member 17. The paper guide member 17 reforms a curl imparted by the heating roller 2 curl into the original state, even if the paper 10 sticks to the heater roller 2 until the point c.
