Abstract: An image forming apparatus includes an image bearer, a charging device that charges a surface of the image bearer, a latent image forming device that forms a latent image on the image bearer, a developing device that develops the latent image on the image bearer with a spherical toner into a toner image, a transfer device that transfers the toner image to a transfer material, and a cleaning device that removes the spherical toner remaining on the image bearer after the toner image is transferred to the transfer material. The cleaning device including a cleaning roller that removes the spherical toner on the image bearer while rotating and contacting the image bearer and which has a greater coefficient of static friction than the surface of the image bearer. An electric field is formed between the cleaning member and the image bearer by applying a voltage to the cleaning member so that the spherical toner adhered onto the image bearer is electrostatically attracted to the cleaning member. The cleaning member may also include a brush roller having bristles planted in a specific configuration.

Abstract: A cleaning device of the present invention is configured to remove toner left on an image carrier after the transfer of a toner image from the image carrier to a recording medium. A rotatable cleaning roller contacts the image carrier for removing the toner left on the image carrier. A rotatable brush roller is positioned upstream of the cleaning roller in the direction of rotation of the image carrier and rubs against the surface of the image carrier and that of the cleaning roller. The cleaning device is free from defective cleaning despite the use of spherical, dry toner grains capable of forming high-quality toner images.

Abstract: A dictionary retrieval device is constructed by a conversion character definition form for providing group IDs for character subsets, a character-group ID conversion part for replacing a character with a group ID, an input character string conversion part for converting the input character string input from the input part to an input group ID, a dictionary conversion part for converting a word dictionary to a converted word dictionary defined by a notation group ID string, and a dictionary retrieval part for retrieving the converted word dictionary by the input group ID string. The dictionary retrieval device can retrieve a word from a dictionary which could not have been retrieved from a dictionary due to an input error, in the past, by regarding elements of character set defined by a conversion character definition form as the same element.

Abstract: An image forming apparatus including an image bearer; a nip forming member, a nip width changing device, a power source; and a controller. The controller switches between a first mode and a second mode according to a predetermined condition. In the first mode, a duty of the transfer bias is a first duty and a width of a transfer nip is a first width. In the second mode, the duty of the transfer bias is a second duty lower than the first duty and the width of the transfer nip is a second width greater than the first width. The duty is (T−Tt)/T×100% where T denotes one cycle of the transfer bias, and Tt denotes a time period, in which the transfer bias is on a transfer-directional side relative to a time-averaged value of the transfer bias, in the one cycle.

Abstract: A belt tracking system for controlling the lateral position of a movable belt entrained about a plurality of generally parallel rollers for moving in a trans-axial direction perpendicular to an axial direction in which the rollers extend parallel to each other includes a roller shaft, a slidable member, and a rotation restrictor. The roller shaft extends outward in the axial direction from an axial end of a specific one of the plurality of generally parallel rollers. The slidable member is slidably disposed around the roller shaft to move along the roller shaft as the belt moves laterally outward in the axial direction. The rotation restrictor is disposed adjacent to the slidable member to restrict rotation of the slidable member around the roller shaft.

Abstract: According to an embodiment, provided is a transfer device including: a nip forming member that abuts against a surface of an image carrier carrying a toner image; and a transfer voltage application unit that applies a transfer voltage including a DC component and an AC component. The transfer voltage is an alternating voltage in which a supply voltage having polarity in a transfer direction and a return voltage having polarity opposite. A time average value Vave of the transfer voltage is set to be at polarity in the transfer direction and is set to be closer to a peak value Vt of the supply voltage relative to a center value Voff between a maximum and minimum value. An absolute value of the peak value Vr of the return voltage is set to be larger than an absolute value of the time average value Vave.
