Abstract: A vehicle front body structure which includes: a pair of side members extending in a vehicle longitudinal direction; a bumper reinforcing member connected to front ends of the side members; a cross member connected to bottoms of the side members in the vicinities of the front ends thereof; and a connecting member connected to the bumper reinforcing member and the cross member. Connection strength between the connecting member and the bumper reinforcing member in the vehicle longitudinal direction is lower than a flexural strength of the cross member in the vehicle longitudinal direction.

Abstract: A developer for developing an electrostatic latent image is disclosed. It is obtained by mixing a chargeable magnetic toner mainly composed of a binder resin and magnetic powder, which toner has a volume resistivity of 10.sup.13 .OMEGA..multidot.cm or greater, with a magnetic carrier having a volume resistivity of 10 .OMEGA..multidot.cm or greater and less than 10.sup.6 .OMEGA..multidot.cm at a weight ratio of between 10:90-90:10. A method of forming an image is also disclosed. An electrostatic latent image is formed on an image carrier. A magnetic brush formed of the developer slides against the surface of the image carrier. The visualized toner image is transferred to a recording medium. The previously-applied toner remaining on the surface of the image carrier is removed after transferring is completed and an electrostatic latent image is visualized when the magnetic brush slides against the surface of the image carrier.

Abstract: A developing method in which a recording region is formed between a movable image carrying element made of a photo-semiconductive material with light-transmitting properties and a hollow-cylindrical, non-magnetic sleeve opposing the image carrying element and accommodating a permanent magnet with a plurality of magnetic poles thereon. An optical signal corresponding to an original is radiated onto the recording region from the back surface of the image carrying element so that toner in a magnetic developer supplied onto the sleeve, and conveyed to the recording region by relative movement of the sleeve and the permanent magnet is selectively adhered onto the surface of the image carrying element. The magnetic developer is a mixture of a toner capable of being charged into a same polarity as the image carrying element, and magnetic particles capable of being charged into either the opposite or same polarity with respect to that of the toner. The toner has a volume resistivity of not less than 10.sup.12 .OMEGA.
