摘要： To provide an image forming apparatus capable of increasing the life of a rotating cam while preventing the occurrence of a shock jitter and transfer failure. The image forming apparatus is configured to execute a forced movement process for rotating the rotating cam to forcibly move a secondary transfer roller against a biasing force of a bias coil spring at a pre-entry timing prior to the entry of the front edge of a recording sheet into a secondary transfer position, and a pressure intensifying process for rotating the rotating cam to increase transfer pressure at a timing immediately after the entry of the front edge of the recording sheet into the secondary transfer position. As the forced movement process, the image forming apparatus executes, alternately, a first forced movement process for normally driving and rotating the rotating cam, and a second forced movement process for inversely driving and rotating the rotating cam, at a predetermined timing.

摘要： An image forming apparatus includes a transfer device to transfer a toner image from an image bearing member onto a recording medium, disposed opposite the image bearing member, a transfer bias power source to apply, between the image bearing member and the transfer device, a superimposed transfer bias in which a direct current (DC) component and an alternative current (AC) component are superimposed to transfer the toner image borne on the image bearing member to the recording medium, and a controller to change the superimposed bias that the transfer bias power source applies. The controller changes the levels of the DC component and the AC component of the superimposed transfer bias in a color mode from that in a monochrome mode to secure a return electric field in the superimposed transfer bias by which the toner is returned from the recording medium to the image bearing member.

摘要： An image forming apparatus includes an image bearing member to bear a toner image charged with a predetermined polarity, and a power source to apply a bias to a transfer portion to transfer the toner image from the image bearing member to a recording medium, a polarity of the bias being changed alternately. The toner image formed with toner of a plurality of colors is transferred in a color mode and the toner image formed with toner of a single color is transferred in a monochrome mode. The bias includes a peak voltage with a polarity that returns toner from the recording medium to the image bearing member. An absolute value of the peak voltage in the color mode is equal to or greater than an absolute value of the peak voltage in the monochrome mode.
