摘要： An image forming apparatus includes an image bearer, a developing unit configured to develop a latent image formed on the image bearer with a toner to form a toner image, and a transfer member including a contact area that comes in contact with the image bearer. The toner image is primary transferred from the image bearer to the transfer member. A speed difference between the image bearer and the transfer member at the contact area is 0.1% or greater but 0.8% or less. The toner has an average circularity of 0.971 or greater but 0.986 or less and a shape factor SF-2 of 110 or greater but 119 or less. The speed difference is represented by the following formula:
[Speed Difference] Speed difference[%]={V1−V2)/V2}×100 where V1 is a linear speed of the image bearer, and V2 is a linear speed of the transfer member.

摘要： A probe apparatus includes a mounting table having a mounting table main body and a chuck top, cylinder mechanisms surrounding a mount of the chuck top, and a connecting mechanism to releasably connect the cylinder mechanisms to a head plate horizontally supporting a probe card. When a semiconductor wafer, mounted on the mount, comes into contact with probes of the probe card, a control unit operates the cylinder mechanisms and the connecting mechanism to connect the cylinder mechanisms to the head plate. Thereafter, the control unit further operates the cylinder mechanisms, to move the chuck top upward from the mounting table main body by a predetermined overdrive amount. Accordingly, the probe apparatus achieves an originally required contact load between the semiconductor wafer and the probes of the probe card while preventing the probe card from being displaced upward during overdriving of the semiconductor wafer, thereby enabling a highly reliable test.
