Disclosed is an upper vehicle body structure (20) having a groove (31) between an outside panel (28) and a roof panel (24). The upper end of a center pillar stiffener (34) overlaps with a roof side stiffener (41). The roof side stiffener (41) is joined to a roof arch (23) at the groove (31). The upper end of a center pillar reinforcing member (33) inside the center pillar stiffener (34) is joined to an end (25b) of a corner gusset (25) at a position below the grooves (31), the other end (25a) of the corner gusset being connected to the roof arch (23). With this, concentration of impact load to the corner gusset (25) can be avoided.

An image forming apparatus includes a first pair of rotary members pressing against each other, forming a first nip therebetween, a cover sheet supply unit to transport to the first nip a cover sheet to be superimposed on an imaging surface of a recording medium, a separation unit that separates the cover sheet from the recording medium after the recording medium passes through the first nip and includes a second pair of rotary members pressing against each other, forming a second nip therebetween, and a drive unit to rotate the first and second pairs of rotary members in both a normal direction for transporting the cover sheet in a supply direction and a reverse direction. The first and second pairs of rotary members and the drive unit together form a cover sheet return mechanism for returning the cover sheet separated from the recording medium to the supply position.
摘要:
When a gloss application sheet is conveyed through a nip formed between a first nip formation member and a second nip formation member pressing against each other, the gloss application sheet is sandwiched between the first nip formation member and a recording medium simultaneously conveyed through the nip. The gloss application sheet includes a first contact surface contacting the first nip formation member and a second contact surface disposed opposite the first contact surface for contacting the recording medium. The first contact surface has a reduced adhesive force compared to the second contact surface.

An image forming apparatus includes an image carrying member, an image writing unit, a development unit, a transfer device, a charging device, and a toner charge control device. The image writing unit forms a latent image on the image carrying member, which is developed as a toner image by the development unit, and the toner image is transferred to a transfer member by the transfer device. The charging device charges the image carrying member and toner on the image carrying member. The toner charge control device, controls a polarity of charge and charging voltage level of toner remaining on the image carrying member. The toner charge control device includes an endless belt having a surface made of a conductive material, a support member extending the endless belt pressed against the image carrying member, and a bias voltage applicator for supplying a voltage to the surface of the endless belt.

In a fixing device, an opposing member contacts a heating member to form a fixing nip between the heating member and the opposing member. A driver rotatively drives at least one of the heating member and the opposing member. A sheet supplier supplies and conveys a sheet to the fixing nip. A recording medium bearing an unfixed toner image is conveyed through a gap between the sheet and the opposing member at the fixing nip with a side of the recording medium bearing the unfixed toner image facing the sheet. At least one of the rotating heating member and the rotating opposing member applies a driving force to the sheet supplied to the fixing nip while the sheet contacts the sheet supplier to apply tension to the sheet at a position upstream from the fixing nip in a sheet conveyance direction.
摘要:
An image forming device in which even if spherical toner made by the polymerization method is used, the toner can be preferably cleaned with a cleaning blade. The image forming device includes a process unit having a photoconductive member and a drum cleaning device that removes toner remaining after transfer from the surface of the photoconductive member, and a transfer unit that transfers the toner image on the photoconductive member to an intermediate transfer belt. A plate shaped cleaning blade that contacts the surface of the photoconductive member to scrape off the toner on the surface of the photoconductive member is used as the drum cleaning device. A photoconductive member having a static coefficient of friction with a sheet as measured by the Euler belt type coefficient of friction measurement method of 0.5 or greater is used as the photoconductive member. Also, a cleaning blade having a static coefficient of friction with a polytetrafluoroethylene tape in the range 1.0 to 2.0 is used as the cleaning blade.
摘要:
A toner container includes a substantially tetrahedral toner-containing portion having an openable edge to discharge toner contained in the toner-containing portion, and a reference fold along which the toner container is foldable after the openable edge is opened. The reference fold extends from the openable edge and is provided on medians of two triangular faces of the toner-containing portion adjoining each other along the openable edge.
摘要:
A structure for a side portion of a vehicle body that is configured such that the ends of an arch member are mounted to rail members extending in the front-rear direction of the vehicle body and such that a roof panel is supported by the arch member. The structure includes the rail members; the arch member, which extends in the width direction of the vehicle and the ends of which are mounted to the rail members; and the roof panel supported by the arch member. In each of the rail members, an outer extension section is integrally provided to a rail outer section and an inner extension section is integrally provided to a rail inner section. The arch member is provided with an arch upper member that can be installed on the outer extension section and an arch lower member that can be installed on the inner extension section.
