    摘要： A long-life electrophotographic photosensitive body having excellent wear resistance and crack resistance can be obtained by using a polycarbonate resin composition, which is obtained by blending 0.01-5 parts by weight of a silicone-modified polyurethane per 100 parts by weight of a polycarbonate resin, as a binder for photosensitive layer (or in case when the photosensitive layer is of multilayer type, for at least an electron transport layer) of the electrophotographic photosensitive body. The silicone-modified polyurethane is obtained by reacting a diol component (a) represented by the general formula (I) below, an active hydrogen-containing polysiloxane compound (b), a polyisocyanate component (c) and, if necessary, a chain extender (d). (In the formula (I), R1 and R2 independently represent a hydrogen atom or an alkyl group; R3 represents a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom or an alkoxycarbonyl group; M represents a single bond, a substituted or unsubstituted alkylene group or an oxyalkylene group; and n represents an integer of 0-4.

    摘要： An image forming apparatus includes a latent image bearer having a shaft to rotate in a normal direction for image formation and a reverse direction, a charging device, a latent image forming device, a developing device including a developer bearer having a shaft, a driving source, a drive transmission device to transmit a driving force from the driving source to the shaft of the latent image bearer and the shaft of the developer bearer. The developer bearer rotates in a predetermined direction during image formation and transports developer including toner to a developing range facing the latent image bearer, thereby developing the latent image on the latent image bearer. The drive transmission device is configured to inhibit transmission of the driving force to the shaft of the developer bearer when the latent image bearer rotates in the reverse direction.
