摘要： Electrophotographic printing techniques offer excellent image quality, but image adhesion to a desired substrate may be problematic in many instances. Primer coatings for improving image adhesion to a substrate may be formed from primer compositions comprising a fluid and an amine-functionalized copolymer dispersed in the fluid as an emulsion, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer. The fluid may be aqueous or organic. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group. The at least one amine group comprises a side chain of the amine-functionalized copolymer.

摘要： An image forming apparatus includes an image bearing member, an intermediate transfer member, a reinforcing member, and a collection unit having a contact member and a support member. The contact member extends in a longitudinal direction that is orthogonal to an intermediate transfer member movement direction. One end of the contact member is fixed to the support member and the other end is in contact with the intermediate transfer member as a free end. When a maximum region in the longitudinal direction where an image is formable on a transfer medium having a maximum size that is supported by the image forming apparatus is defined as an image forming region, at least part of the reinforcing member is located outside the image forming region and, on one end side of the contact member, the reinforcing member is provided on an inner side than the end of the contact member.

摘要： A transfer member for a printing device includes a shaft, a rigid cylindrical core member, mounted on the shaft, an outer layer supported on the rigid cylindrical core member, and optionally a conformable intermediate layer, spacing the cylindrical core member from the outer layer. The outer layer defines an outer surface of the transfer member, and is configured for receiving a toner image thereon. The cylindrical core and outer layer have a same axis of rotation as the shaft. The rigid cylindrical core and/or the conformable intermediate layer, where present may be electrically biased, relative to a photoconductor drum of the printing device.

摘要： A transfer device includes a movable component, a moving assembly, a restrictor, and an operating member. The movable component moves toward and away from a latent image bearer unit. The moving assembly causes the movable component to move toward and away from the latent image bearer unit. The restrictor restricts the latent image bearer unit from detaching from an image forming apparatus. The operating member causes the moving assembly to move the movable component away from the latent image bearer unit and releases restriction of detachment of the latent image bearer unit from the image forming apparatus by the restrictor.
