An apparatus and methods of decorating a metallic container are provided. More specifically, the present invention relates to apparatus and methods used to provide a decoration or indicia on a predetermined portion of an outer surface of a metallic container body. The decorator includes at least one digital print unit, a transfer blanket, and a support element. The digital print unit transfers a decorating material to the transfer blanket to form a decoration on the transfer blanket. The support element then moves a metallic container into contact with the transfer blanket. In this manner, the decorating material is transferred to an exterior surface portion of the metallic container to decorate the metallic container. In one embodiment, the digital print unit is an electrophotographic system which transfers a toner material to the transfer blanket. In another embodiment, the digital print unit includes an inkjet print head which transfers an ink to the transfer blanket. Optionally, the decorator may include two or more support elements.

An image forming apparatus includes a photoconductor, an exposure device, and a shutter assembly. The exposure device includes a light source configured to expose the photoconductor. The light source is repositionable between a proximity position at a first distance from the photoconductor and a separation position at a second distance from the photoconductor. The first distance is less than the second distance. The shutter assembly is configured to move away from the light source in response to the light source moving toward the proximity position. The shutter assembly is configured to move to cover the optical path of the light source in response to the light source moving toward the separation position.

A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member. The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.

An image forming apparatus includes a photosensitive member, a charging member, an electrostatic image forming portion, a developing member, a transfer member, a transfer voltage source, a brush member, a brush voltage source, and a controller capable of executing a cleaning operation. The controller carries out control so that the cleaning operation includes a first operation in which a potential difference is formed between the transfer member and the photosensitive member so that toner charged to a normal charge polarity is moved from the transfer member toward the photosensitive member, and a second operation in which a potential difference is formed between the brush member and the photosensitive member so that the toner charged to the normal charge polarity is moved from the photosensitive member toward the brush member.

A method of printing includes, applying to an intermediate transfer member (ITM) (44), one or more fluids that include at least a printing fluid for forming an image on the ITM (44). At least part of the image is transferred from the ITM (44) to a target substrate (50). Residues of the one or more fluids that were not transferred to the target substrate (50) and remained on the ITM (44), are transferred from the ITM (44) to one or more rotatable elements (112), and the residues are removed from the one or more rotatable elements (112).

In an image forming apparatus, a tray having first and second receiving portions is configured to move between a first position, at which at least part of the tray is positioned inside an apparatus body, and a second position, at which the tray is outside the apparatus body. The tray in the first position allows a first recording medium to be conveyed from the first receiving portion. When the tray is in the first position, the second receiving portion is configured to move between a third position, which is at an upstream side relative to a first opening of the apparatus body in a second direction, and a fourth position, which is at a downstream side relative to the third position in the second direction. The second receiving portion at the third position allows a second recording medium to be conveyed from the second receiving portion in the second direction.

A conductive roller includes a support member, an elastic layer disposed on an outer peripheral surface of the support member, and a surface layer disposed on an outer peripheral surface of the elastic layer. The elastic layer includes a cylindrical elastic foam and a conductive covering layer covering an exposed surface of the elastic foam and has a volume resistance value of 10.sup.5Ω or less at an applied voltage of 10 V. The elastic foam has a conductive particle content of 1% by mass or less based on the total mass of the elastic foam.

An electrophotographic roller includes: a mandrel and an elastic layer on the mandrel, and having a crown shape in which a diameter decreases from a central position O in a longitudinal direction of the mandrel toward an end portion. When a position of the end portion in the longitudinal direction of the elastic layer is defined as X2, a position between the O and the X2 is defined as Xl, a distance between the O and the X1 is defined as L1, and a distance between the X1 and the X2 is defined as L2, L1=0.6×(L1+L2). When outer diameters of the electrophotographic roller at O, X1 and X2 are defined as Do, DX1 and DX2, respectively, and Z1=(Do−DX1)/2 and Z2=(DX1−DX2)/2 are defined, Z1, Z2, L1 and L2 satisfy (Z2/L2)<1.931×(Z1/L1).

An image forming apparatus includes: a rotatable transfer cylinder with a first groove formed in an outer portion thereof in a rotational radial direction that causes an image to be transferred to a recording medium when it passes along an outer surface of the transfer cylinder; a rotatable fixing cylinder that has a second groove formed in an outer portion thereof in a rotational radial direction, that causes the image transferred to the recording medium to be fixed thereto when the recording medium passes along an outer surface of the fixing cylinder; a loop-shaped circulating member that is wrapped at least around the transfer and fixing cylinders, that circulates in response to rotations of the transfer and fixing cylinders; a recording medium holding member supported by the circulating member, disposed in the first groove when the holding member passes along the transfer cylinder and disposed in the second groove when the holding member passes along the fixing cylinder; first and second driving units that rotate the transfer and fixing cylinders respectively; and that is configured such that a ratio of a moment of inertia of the fixing cylinder to an output torque of the second driving unit is set to be greater than a ratio of a moment of inertia of the transfer cylinder to an output torque of the first driving unit.

An image forming apparatus includes: an image forming unit configured to form an image on an intermediate transfer member; a transfer member configured to output a transfer voltage, in order to cause a transfer current to flow so as to transfer the image to a sheet; a first measurement unit configured to measure a density of the image; and a control unit configured to: control the image forming unit to form a test image on the intermediate transfer member based on test image data; control the first measurement unit to acquire a measured density of the test image; correct the measured density based on an evaluation value of an electric resistance of a path through which the transfer current flows; and generate data for density correction, based on the test image data and a corrected measured density.
