An image forming apparatus includes an image carrier, an exposure device, a developing device, a primary transfer device, a secondary transfer device, and a control unit. The exposure device exposes the image carrier to form an electrostatic latent image on the image carrier. The developing device forms a toner image by developing the electrostatic latent image using toner. The primary transfer device primarily transfers the toner image to a transfer body. The secondary transfer device applies a transfer bias to secondarily transfer the toner image to a recording medium. The control unit applies a cleaning bias to the secondary transfer device to remove residual toner after the secondary transfer. When the control unit determines that the toner image based on the exposed electrostatic latent image is not secondarily transferred at a predetermined timing, the first cleaning processing is performed until the subsequent processing is started.

An image forming apparatus includes an image holding member, a charging unit that charges a surface of the image holding member, an electrostatic charge image forming unit that forms an electrostatic charge image on the charged surface of the image holding member, a developing unit that includes an electrostatic charge image developing toner and that develops the electrostatic charge image on the surface of the image holding member with the electrostatic chare image developing toner to form a toner image, an intermediate transfer body having a circumferential surface of which micro rubber hardness is in a range of 45 to 65, a first transfer unit that first transfers the toner image formed on the surface of the image holding member to a surface of the intermediate transfer body, and a second transfer unit that second transfers the toner image transferred to the surface of the intermediate transfer body to a recording medium, wherein the electrostatic charge image developing toner satisfies the following formulae
(ln (T1)ln (T2))/(T1T2)0.14,
(ln (T2)ln (T3))/(T2T3)0.15, and
(ln (T1)ln (T2))/(T1T2)<(ln (T2)ln (T3))/(T2T3)
wherein (T1) represents a viscosity of the electrostatic charge image developing toner at 60 C., (T2) represents a viscosity of the electrostatic charge image developing toner at 90 C., and (T3) represents a viscosity of the electrostatic charge image developing toner at 130 C.

An image forming apparatus includes a rotatable image bearing member, a developing member, a transfer member, and a brush contacting a surface of the image bearing member in a contact portion downstream of a transfer portion and upstream of a developing portion with respect to a rotational direction of the image bearing member. The toner which is not transferred onto a toner image receiving member is collected by the developing member. In a charging series, the toner is positioned on the same side as a normal charge polarity of the toner relative to the brush. In the contact portion, a maximum value of a contact pressure of 0.7 gf/mm.sup.2 or more and 3.5 gf/mm.sup.2 or less, a maximum contact area ratio is 18% or more and 74% or less, and a Clark-Evans index of the brush is 1 or more.

An intermediate transfer device includes: an endless belt that circulates, receives transfer of a toner image at a first transfer position, and holds the toner image until the toner image reaches a second transfer position at which the toner image is transferred to a transfer receiver; a first cleaning unit that is disposed downstream of the second transfer position and upstream of the first transfer position in a circulation direction of the belt and removes residual toner from the belt after transfer; and a second cleaning unit that is disposed downstream of the first cleaning unit and upstream of the first transfer position in the circulation direction and removes residues from the belt after removal by the first cleaning unit, in which the second cleaning unit includes: a contact cleaning part that extends in a width direction intersecting the circulation direction and is in contact with the belt; and a support guide receiving part that supports the contact cleaning part, and receives a guide for attachment to and detachment from an image forming apparatus main body by sliding in the width direction.

A transfer device includes first and second assemblies, a spring, and a moving mechanism. The first assembly is rotatable around a first rotation shaft. The first assembly includes an endless belt, and a transfer roller that presses a sheet against an image transport belt to transfer a toner image onto the sheet. The second assembly is rotatable around a second rotation shaft. The second assembly includes a cleaning blade that abuts a leading end edge thereof against a portion of the endless belt. The spring biases the second assembly to rotate around the second rotation shaft. The moving mechanism moves the transfer roller to be in contact with and separated from the image transport belt. The first assembly rotates around the first rotation shaft as the transfer roller moves. The second assembly follows the rotation of the first assembly to rotate around the second rotation shaft.

A cleaning device for a rotational body is provided. The cleaning device includes a scraping portion whose edge is pressed against a rotational body to which toner adheres. The scraping portion scrapes the toner off the rotational body. The cleaning device also includes a guide portion that guides a recording medium toward the rotational body, and a guide support portion that supports the guide portion. The guide support portion is disposed at a position separated from the scraping portion in a state in which the guide support portion is pressed by the guide portion that is guiding the recording medium.

An endless-shaped electrophotographic belt with a cleaning blade provides improvement in transfer remaining toner wiping properties. The electrophotographic belt has an endless shape including, on an outer circumferential surface thereof, grooves and lands. The grooves extend in a circumferential direction of the belt and the lands are positioned between the grooves. The belt further has on the outer circumferential surface, one or more convex portion(s) between at least one of the grooves and one of the lands adjacent to the one of the grooves, and in a cross section of the belt in a direction orthogonal to a direction of which the grooves extend, the convex portion(s) projects more than the lands.
