20090169236 | LUBRICANT APPLYING DEVICE AND IMAGE FORMING APPARATUS - In a lubricant applying device, a position adjusting member adjusts relative positions of a lubricant and a rotating member. The rotating member rotates while in contact with the lubricant, receives the lubricant, and applies the lubricant to an image carrier in an image forming apparatus. | 07-02-2009 |
20120020698 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member to bear a toner image, a waste toner storage mechanism to store residual toner, and an intermediate transfer unit detachable from the image forming apparatus. The intermediate transfer unit includes an intermediate transfer member onto which the toner image is transferred, a cleaning device to remove residual toner remaining on the intermediate transfer member after the toner image is transferred to a recording medium, and a connecting mechanism to connect the cleaning device and the waste toner storage mechanism. The connecting mechanism includes a movable connecting tube and a moving device to move the connecting tube between a first position at which the connecting tube engages the cleaning device and the waste toner storage mechanism, and the second position at which the connecting tube separates the cleaning device from the waste toner storage mechanism. | 01-26-2012 |
20120237251 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member to bear a toner image on a surface thereof, an intermediate transfer member disposed facing the image bearing member, onto which the toner image is transferred, a primary transfer device disposed opposite the image bearing member with the intermediate transfer member interposed therebetween to transfer the toner image from the image bearing member onto the intermediate transfer member, a cleaning device detachably attachable relative to the intermediate transfer member and including a cleaning member to contact the surface of the intermediate transfer member to remove residual toner remaining on the intermediate transfer member after transfer of the toner image, and a lubricant application device detachably attachable relative to the intermediate transfer device to apply a lubricant on the surface of the intermediate transfer member. The cleaning device and the lubricant application device are detachably attachable independent of each other. | 09-20-2012 |
20140044463 | IMAGE FORMING APPARATUS - An image forming apparatus includes an image bearing member to bear a toner image, a waste toner storage mechanism to store residual toner, and an intermediate transfer unit detachable from the image forming apparatus. The intermediate transfer unit includes an intermediate transfer member onto which the toner image is transferred, a cleaning device to remove residual toner remaining on the intermediate transfer member after the toner image is transferred to a recording medium, and a connecting mechanism to connect the cleaning device and the waste toner storage mechanism. The connecting mechanism includes a movable connecting tube and a moving device to move the connecting tube between a first position at which the connecting tube engages the cleaning device and the waste toner storage mechanism, and the second position at which the connecting tube separates the cleaning device from the waste toner storage mechanism. | 02-13-2014 |
20140140726 | IMAGE FORMING APPARATUS - An image forming apparatus includes a rotary shaft, a first image bearing member, a nip forming member, a moving device, and a restriction device. The first image bearing member bears a visible image on a surface thereof and is rotatable about the rotary shaft which is driven directly or indirectly. The nip forming member contacts the first image bearing member to form a transfer nip therebetween. The moving device is disposed on the rotary shaft and rotates to move the nip forming member to contact and separate from the first image bearing member. The restriction device inhibits rotation of the moving member in a state in which the nip forming member is separated from the first image bearing member by the rotation of the moving device. | 05-22-2014 |
20150160587 | PROCESS CARTRIDGE CAPABLE OF SUPPRESSING FILMING AND IMAGE FORMING APPARATUS WITH SAME - An image forming apparatus includes a latent image bearer, an electric charging member to electrically charge the latent image bearer uniformly while forming an electric charging nip therebetween by contacting the latent image bearer. A value obtained by dividing a moment of inertia of area of the latent image bearer by the cube of length thereof ranges from about 0.000058 [mm] or more to about 0.000145 [mm] or less. A width of the electric charging nip in a direction of rotation at longitudinal ends of the latent image bearer is larger than that at a longitudinal center thereof. A difference between the width of the electric charging nip in the direction of rotation at the longitudinal ends of the latent image bearer and that at the longitudinal center thereof is larger than an amount of deformation of the latent image bearer generated during rotation at the longitudinal center thereof. | 06-11-2015 |
20150248075 | CHARGING DEVICE AND IMAGE FORMING APPARATUS INCORPORATING SAME - A charging device includes a charger and a power supply circuit. The charger is disposed opposing a latent image bearer. The power supply circuit applies to the charger an alternating voltage obtained by superimposing a pulsating voltage on a direct-current voltage. The alternating voltage generates normal discharge from the charger to a surface of the latent image bearer and reverse discharge from the surface of the latent image bearer to the charger. A pulse ON time of a voltage component toward a reverse discharge side relative to a desired surface potential Vde of the latent image bearer is shorter than a pulse ON time of a voltage component toward a normal discharge side relative to the desired surface potential Vde of the latent image bearer. | 09-03-2015 |
